Abstract
Recently discovered SARS-CoV-2 caused a pandemic that triggered researchers worldwide to focus their research on all aspects of this new peril to humanity. However, in the absence of specific therapeutic intervention, some preventive strategies and supportive treatment minimize the viral transmission as studied by some factors such as basic reproduction number, case fatality rate, and incubation period in the epidemiology of viral diseases. This review briefly discusses coronaviruses' life cycle of SARS-CoV-2 in a human host cell and preventive strategies at some selected source of infection. The antiviral activities of synthetic and natural polymers such as chitosan, hydrophobically modified chitosan, galactosylated chitosan, amine-based dendrimers, cyclodextrin, carrageenans, polyethyleneimine, nanoparticles are highlighted in this article. Mechanism of virus inhibition, detection and diagnosis are also presented. It also suggests that polymeric materials and nanoparticles can be effective as potential inhibitors and immunization against coronaviruses which would further develop new technologies in the field of polymer and nanoscience.

Introduction
Following a series of human coronaviruses that have plagued the pages of human history [1], the newly discovered severe acute respiratory syndrome–coronavirus-2 (SARS-CoV-2) (Fig. 1) has emerged to become the highest risk to the global health care system, causing a worldwide outbreak of over hundred eighty million cases as of July 2, 2021. Coronaviruses resemble each other in their morphology and chemical structure; they are primarily zoonotic and found in avians and mammals. These viruses have been transmitted to the human system after being incubated through various animal’s hosts, causing severe acute illnesses and serious public health concerns across the globe.
Coronaviruses belong to the Coronaviridae family of the order nidovirales. The family Coronaviridae divided into two subfamilies named as Coronavirinae and Torovirinae. Coronavirinae is further subdivided into four genera called Alphacoronavirus (Alpha-CoV), Betacoronavirus (Beta-CoV), Gammacoronavirus (Gamma-CoV), and Deltacoronavirus (Delta-CoV). In contrast, Torovirinae has been further divided into Bafinivirus and Torovirus based on phylogenic relationships (Fig. 2). Alpha-CoV comprises human coronaviruses (HCoV) such as HCoV-229E and HCoV-NL63, while Beta-CoV targets a wide range of mammalians, including mice and humans with HCoV-HKU1, HCoV-OC43, SARS-CoV, Middle East respiratory syndrome coronavirus (MERS-CoV), murine coronavirus (MHV) and bovine coronavirus (BCoV). The Gamma-CoV and Delta-CoV infect mainly birds except for a beluga whale coronavirus that infects mammals. The Delta-CoV genus was discovered in 2012 and regrouped in different Coronavirus (HKU11, HKU12, HKU13) belonging to mammals to birds. Presently, seven strains of known human coronaviruses include 229E, NL63, OC43, HKU1, SARS-CoV, MERS-CoV, and SARS-CoV-2 [2]. The last three proved to be highly pathogenic that encountered wider host adaptability and competence to cause severe diseases in humans, mice, chickens, cats, camels, dogs, pigs, civet cats, and bats (Fig. 3). An Alpha-CoV, HCoV-229E and then a Beta-CoV, HCoV-OC43 was discovered in 1966 and1967, respectively. After a large gap, two more Beta-CoV, SARS-CoV and MERS-CoV, were first found in Hong Kong, China, and Jeddah, Saudi Arabia, in the years 2003 and 2012, respectively. At the end of 2019, SARS-CoV-2 identified in humans first time in Wuhan, China, in December 2019 and is the cause of Coronavirus disease -2019 (COVID-19) (Fig. 4).
The SARS-CoV recorded around 8000 infected cases with a mortality rate of 10% in 26 countries. In contrast, MERS-CoV recorded about 2500 infected cases in 27 countries, primarily in the Middle- East, with a higher mortality rate (about 35%) [3, 4]. The newly emerged SARS-CoV-2 has recorded greater than one hundred eighty million cases with a 2.17% global average fatality rate in more than 200 countries as of July 2, 2021 [5]. This novel human coronavirus has significantly impacted the economy and the health care systems worldwide, causing radical changes in people's everyday habits and lifestyles across continents. Basic reproduction number (R0), case fatality rate (CFR) and incubation period are the three most common factors extensively studied in the epidemiology of diseases. A comparison of these three factors for the nine most widespread epidemics of all time have been represented in Table 1 [6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,27,28,29,30,31,32].
SARS-CoV-2 has a unique single strain of RNA virus that causes COVID-19 with respiratory and gastrointestinal illness in both humans and animals. It can be transmitted through respiratory droplets with direct/indirect contacts and characterized by distinct medical signs and symptoms. Few incidences of gastrointestinal symptoms such as diarrhoea up to 4% [33] and some early signs of loss of smell/taste were also reported [34]. Since there is no effective medication is available against the virus, supportive treatment with repurposed drugs and broad-spectrum antibiotics, antiviral nanoparticles provide relief to the patients in many countries and some preventive strategies to block the routes of transmission of this infectious disease (Fig. 5). The major attribution is the restriction in the movement of the people, disinfection of patient handling equipment, use of personal protective equipment, early diagnosis, avoiding close contact with the diseased person, and mildly infected people were isolated in the residence or outpatient environment [35,36,37,38,39]. Washing hands, physical distancing, sanitization, and other practices must be followed as per the guidelines. The immune system, which can be enhanced by regular exercise and a balanced diet, reduces the virus's effect [40].
Recently, few polymeric materials have demonstrated antiviral capabilities [41,42,43,44,45,46,47], which can prevent or inhibit the spread of a virus by (a) providing a semipermeable barrier (e.g. a mask or face-shield), (b) interfering with binding to the glycoprotein surface of host cells, (c) augmenting small molecular antiviral drug therapies, (d) enhancing the response of the immune system as a vaccine adjuvant, or (e) as a vehicle for other therapeutic molecules to improve the water solubility or stability of antiviral therapeutics.
The objective of this review is to highlight the epidemic caused by SARS-CoV-2 and the importance of natural, synthetic or modified polymeric materials and nanoparticles that can be used to inhibit the virus entry into the cellular receptors due to its promising antiviral activities. Therefore, these materials may be utilized as an inhibitor for the deadly spreading of SARS-CoV-2. In addition, the mechanism of viruses in the human body (Fig. 6) and the mechanism of virus inhibition reported by different researchers are summarized in this review with a short perspective of the polymeric approach toward the treatment of this new type of coronavirus.
Polymeric Materials
The investigation with polymeric materials and nanoparticles (NPS) as an antiviral agent has been successfully carried out for many years, producing unique classes of materials that hold promise for conquering these hurdles. It can directly inhibit viral replication and infection, usually by binding to the virus and preventing it from invading a host cell. Both natural and synthetic polymers show the ability to be used for antiviral treatment. The natural polymers include cyclodextrin, chitosan, carrageenans, whilst the synthetic polymers are polyethyleneimine (PEI), poly (dl-lactide-co-glycolide) (PLGA), dendrimers and metal and metal oxide NPs, namely silver, copper, titanium, zinc and gold, have been introduced as effective antiviral agents.
Chitosan
Chitosan is a natural linear polysaccharide composed of randomly distributed β-(1 → 4)-linked D-glucosamine (deacetylated unit) and N-acetyl-D-glucosamine (acetylated unit). It gained interest not only for its natural abundance but also for its unique antiviral, antibacterial, anti-inflammatory activities, biocompatibility, biodegradability, non-toxicity, and extreme moldable properties [48,49,50,51,52,53]. Thus, it has broad prospects in biomedical science and potential applications in gene therapy, material science, biotechnology, food industry, cosmetics, environmental protection, agriculture, and even wastewater treatment [54]. Chitosan is a deacetylated derivative of chitin (Fig. 7), a naturally occurring polymer in shrimp, squid, and crab shells [55, 56]. Some of the acetamide (-NHCOCH3) functional groups of chitin are transformed into primary amine (-NH2) functional groups through an incomplete deacetylation process. Because of this, the glucose portion of chitosan contains a randomly distributed acetylated (-NHCOCH3) and deacetylated -NH2 groups along the chain. The ratio of 2-acetamido-2-deoxy-D-glucopyranose to 2-amino-2-deoxy-D-glucopyranose structural units is known as the extent of acylation has a notable effect on chitin solubility and solution properties. Various chitosan with different degrees of acetylation (DA) have been synthesized and reported [57].
The presence of amine groups in the structures gives room for modification reactions. Thus, following the successful deacetylation of chitin to produce chitosan, biomedical researchers [58,59,60,61,62] made modifications to the chemical structures of chitosan to produce cationic chitosan derivatives, such as N-(2-hydroxypropyl)-3-trimethylammonium chitosan chloride (HTCC)and N-dodecyl-N-(2-hydroxypropyl)-3-trimethylammonium chitosan chloride (HM-HTCC). HTCC is formed by the reaction of chitosan with glycidyl trimethylammonium chloride, while the HTCC forms the HM-HTCC with N-dodecyl aldehyde. Figure 8 shows the structural difference between the HTCC and HM-HTCC. Due to the random distribution of acetamide and amine groups in the chitosan chain, -R can be either -H or -COCH3. Similarly, in HM-HTCC polymer, -R may be -H or -COCH3 or -C12H25.
Galactosylated Chitosan (GC) hydrophilicity is higher than chitosan when the degree of galactosed chitosan decreased, which indicates that it could be used as a novel promising scaffold for hepatocyte and transplantation. GC is positively charged spherical shape particles having an average diameter of 1.05 nm and standard zeta potential + 15 mV. Due to their novel properties, GC particles can act as passive and active drug targets to the liver [63].
Cyclodextrin
Cyclodextrins (CDs) are non-toxic oligosaccharides with cyclic α-D-glucopyranose units of (α-1, 4)-linkage, hydrophobic interior and hydrophilic exterior. Studies with CD and its derivatives show its ability to form complexes with various drugs in the last two decades. It can further enhance the solubility of water-insoluble drugs during formulations by the inclusion complexation technique. The advantages of the complexed drugs with CDs are their abundance, higher stability, masking of bad test or odor, less volatile nature, minimized side effects, and improved drug release system [64].
Carrageenans
Carrageenans (CGNs) are a family of natural high molecular weight and linear sulfated polysaccharides that are mainly extracted from marine seaweeds. These natural polymers are ionic in nature as they contain about 15–40% ester sulfate content. They are further classified into three groups based on their degree of sulfation (sulfate content), namely kappa (κ), iota (ι) and lambda (λ) carrageenans, containing one, two, and three negatively-charged sulfate ester groups per disaccharide repeating unit, respectively (Fig. 9). Thus, the main differences that influence the properties of κ-CGN, ι-CGN, and λ-CGN are the number of the ester sulfate groups and their relative positions on the repeating galactose units. CGNs polymers of different molecular weights have been used widely to facilitate drug formulation or sustained drug release [65,66,67,68,69,70].
Polyethylenimine
Polyethylenimine (PEI) is one of the important and prominent organic polyamine polymers, also the best example of widely studied polycationic polymers. It can form nano-sized particles by constructing a linkage with the sugar-phosphate backbone of nucleic acids [71]. They are water-soluble, branched synthetic polymer with flexible length and frequently used in vitro and in vivo as a non-viral vector for DNA/RNA transfection and gene silencing. However, their toxicity depends on the molecular weight, and increased branching and higher charge density restrict its usage in human gene therapy [72]. Hence several methods such as covalent binding of polyethylene glycol or several moieties with PEI were used to increase its stability and reduce toxicity [73]. Modifications of PEI using a coating of serum albumin [74], dextran [75], acylation [76] led to enhance the biocompatibility and gene transfer efficiency.
Poly (lactic-co-glycolic acid)
Poly(lactic-co-glycolide) (PLGA) is a well-established biodegradable polymer used in medical devices and drug delivery applications. They are less toxic compared to cationic polymers. By varying the quantity of D, L lactide and glycolide, different forms of PLGA can be obtained [77].
Dendrimers
Dendrimers are highly branched three-dimensional macromolecules with nano-size dimensions and distinctive properties due to their spherical shape and internal empty core space. The empty internal cavity can encase other molecules into its macromolecular cavity and act as coating and prevent those molecules from further oxidation and clustering. These unique properties of dendrimers made them useful as diagnostic agents, antibacterial, antitumor, and biomedical applications [78, 79]. Dendrimers have a definite branched structure with the presence of different compositions and groups included a large surface area in its moiety made a unique spherical shape. These groups can be considered the active functional sites that provide a template for drug immobilization and grafting. The center core of the dendrimer consists of an atom or multifunctional molecule, and branching units form a covalent bond with the central core and terminal functional groups on the external surface. Dendrimers are monodispersing macromolecular units with specific sizes and molecular mass. Due to their reproducible shape and size, they have well-controlled rheological properties. The terminal groups of dendrimers can be controlled to have distinct properties like hydrophilicity or lipophilicity, solubility, miscibility, and acidity. One of the most important features of dendrimers is the ability to encapsulate small size materials such as drugs, metals, and imaging moieties that can fit within their cavities and interact through charge interactions, hydrogen bonding, and lipophilicity. The encapsulation of drugs in dendrimers can increase drug stability, reduce possible drug toxicity, and expedite the drug's targeted and controlled release. Dendrimers are a low-cost base compared to proteins with higher biocompatibility and provide an accurately controlled large macromolecular surface [80]. The dendrimers can encapsulate other biologically active compounds and conjugate molecules, and act as a coating [81]. For each generation of a dendrimer, the number of surface groups rises exponentially while the diameter increases linearly. In addition, the introduction of varied chemical groups such as basic, acidic, hydrophobic, hydrogen-bonding capability, and charges, allows modification and controlling of the chemical properties and architecture of core, branches, and surface groups of dendrimers [82]. These variation of the properties, composition and architecture of dendrimers are the key physicochemical properties that improve theirs in vitro [83] and in vivo [84] behaviours.
G4 -PAMAM (poly amidoamine)dendrimer amine-terminated PAMAM dendrimer used as a coating for the nano Ni material-Ni(NO3)2⋅6H2O, which can exhibit good anti-microbial activity against various bacteria [78]. The nano Ni material usually undergoes rapid oxidation and aggregate during ambient conditions. Dendrimer can encapsulate Ni NPs and act as a coating to prevent them from further oxidation and aggregation. The chemical reaction exhibited by this dendrimer encapsulated Ni nanoparticles prevent bacterial growth by disrupting the cell wall when it was tested against E coli bacteria [85].
Polymeric Nanoparticles (NPs)
NPs based polymers are widely used in medicine as gene carriers. They are colloidal solids with a particle size of 10–100 nm. Due to their very small size, they can do capillary intrusion and absorption by cells, which results in higher concentrations at the target site [86]. Their unique properties such as lower particle size [87], higher surface area to volume ratios [88], tunable surface charge [89], biomimetic properties [90, 91], and the possibility of drug encapsulation [92] help them to be used as a weapon against virus treatment. However, their antiviral properties have been investigated and used for development or improvement purposes only for some viruses like influenza, HIV, and rabies [93, 94]. The metal and metal oxide-based nanoparticles can work as attachment blocking, reproduction inhibitory action, and viral wall and membrane deformation [95].
Mechanism of Inhibition of Viruses
SARS-CoV-2 has caused a worldwide health crisis due to its high infection rate. Several preventive strategies have been adopted to combat this lethal infection include facemask use, vaccine development, repurposed antiviral drugs, and macromolecular neutralizing antibodies [96, 97]. Polymeric materials have been designed as antiviral inhibitors and drug delivery carriers for effective virus inhibition and antiviral drug delivery carriers. It includes natural and synthetic polymeric materials, polymer-based prodrugs, nanoparticles, which show the potential and significantly improve the efficacy of antiviral therapeutic strategies (Table 2 [58, 98,99,100,101,102,103,104,105] and Table 3) [106,107,108,109,110,111,112,113,114,115,116,117,118,119,120,121,122,123,124,125,126,127,128,129,130,131].
Chitosan
Generally, antiviral polymeric drugs have been developed mainly based on the inhibition of the virus's interactions with the host cell. Polymers used their high molecular weight and multivalent binding capability to exert their antiviral activity through steric shielding of the viral surface or competitive inhibition of the interactions [132]. The blocking of host cell receptor from viral docking and entry can be achieved either via polymer binding to the host cell or the virus, both of which leads to a reduction in viral entry (Fig. 10). HTCC polymers with different degrees of substitution have been reported to have an antiviral activity used to treat infections caused by coronaviruses by inhibiting viral replication. Milewska and his co-workers used functional assays, molecular methods, flow cytometry, and confocal microscopy to study the mechanism of HTCC antiviral activity against human coronaviruses [58, 133, 134]. Even though the HTCC polymers do not hamper virus binding to heparan sulfate proteoglycans (HSPs), the polymers interact with the corona viral spike protein and block virus interaction with cellular receptors ACE2 proteins. Recently, the antiviral activity against the pathogenic SARS-COV-2 and MERS-COV using permissive cell lines and human airway epithelium model for in-vitro and ex-vivo, respectively [135]. The result revealed that HTCC efficiently blocked replication of both SARS-COV-2 and MERS-COV. Thus, HTCC polymers with different degrees of substitution are considered potent inhibitors and promising drug candidates for the highly pathogenic SARS-COV-2. HTCC with varying degrees of substitution has a different inhibitory effect on coronaviruses. Though the degree of substitution in HTCC polymers is usually varied between 57 to 77%, different HTCC polymers have different inhibitory of coronaviruses. Table 4 summarizes the HTCC polymers that have the most significant inhibitory effect on different coronaviruses [58, 133,134,135].
Cyclodextrin
The cavity in the CDs allows the encapsulation of hydrophobic groups forming inclusion complexes without modifying the guest's structure and chemical properties [136]. Alternative interaction mechanisms such as forming non-inclusion complexes or the solubilization through aggregates can also be present in CD solutions. Sun et al. [137] discussed the mechanism and production of CD-soluble angiotensin-converting enzyme 2 (CD-sACE2) inclusion compounds treatment of SARS-CoV-2 infections by blocking S proteins. sACE2, the extracellular region of ACE2, retains the enzyme activity of ACE2 and can bind to the S-protein of SARS-CoV, inhibiting SARS-CoV infected cells. Since the infection mechanism of SARS-CoV and SARS-CoV-2 is the same, sACE2 could also inhibit the infection of SARS-CoV-2. The formation of a complex of CD and sACE2 could effectively improve the water solubility of sACE2, so it meets the requirements for drug atomization inhalation. The inclusion conjugates release sACE2 after entering the body via atomization or other drug delivery. The released sACE2 would combine with SARS-CoV-2 S-proteins to block the virus's ability to infect and destroy human cells.
Carrageenans
Carrageenans exhibit antiviral activity against African swine fever virus, rhinovirus, influenza A virus enterovirus, human herpes, and dengue virus [65,66,67,68,69,70, 138]. Very recently, Yejin and his co-workers [102] investigated the efficacy of the sulfated polysaccharide CGN against SARS-CoV-2 spike antibody, and the immunofluorescence microscopy result revealed that λ-CGNs effectively inhibit the SARS-CoV-2 viral infection without the viability of the cell. Moakes and his coworkers [139] recently reported the nasal formulations actively target the removal of SARS-CoV-2. In addition, the spray system, which is a composite mixture containing both gellan and λ-CGNs, has been reported to demonstrate highly potent capacities against SARS-CoV-2 infection in Vero cells, resulting in complete inhibition of the virus. While the gellan systems exhibited limited ability to suppress the SARS-CoV-2 virus, the λ-CGN showed complete inhibition of the SARS-CoV-2 infection over 48 h. However, the highly potent antiviral composite system provided an enhanced mechanical response towards spraying and antiviral activity, a synergistic behaviour from both gellan and λ-CGN. Thus, the spray’s ability to completely inhibit viral infection is attributed to the active polysaccharide λ-CGN component of the spray formulation. The mechanism for the inhibition of the SARS-CoV-2 virus from attacking the host cell receptors is assumed to be either through the creation of a steric barrier across the host cell or around the virus interface, as illustrated in Fig. 11.
Polyethylenimine
The polycationic polymer such as N, N-dodecyl methyl-polyethyleneimine (PEI), can act as a good antiviral agent towards hydrophobic glycoprotein SARS-CoV-2 as reported in the case of the influenza virus, which was protected from the outside by a lipid membrane. Different solid surfaces such as glass, polypropylene, and polyethylene modified with hydrophobic polycationic polymers produce strong surface-protein interaction caused the viral protein loss destroying the virus [140]. However, it has been reported that modified surfaces of polypropylene and polytetrafluoroethylene with hybrid self-assembled monolayers (SAMs) have enhanced binding with spike proteins, eventually disintegrate the coronaviruses [141].
Poly (lactic-co-glycolic acid)/Poly (lactic-co-glycolide) (PLGA) and PLGA NPs
PLGA is a well-established, less toxic biodegradable synthetic copolymer used in FDA-approved pharmaceutical products and medical devices. NPs developed by polymeric materials such as PLGA, PLA, poly(ethylene glycol)-poly(e-caprolactone) (PEG-PCL), and PLA-PEG have been used as nanocarriers drug delivery systems for the antiviral disease treatment [142]. PLGA NPs have been shown preclinical efficacy in antigen vaccines technology like HBs Ag, Malaria antigens, Bacillus anthracis spores to generate extended cellular and humoral immune response as suitable candidates for encapsulating the antigens within the nanocarrier to provide extended and controlled biological release [143].
Dendrimer
Polymeric materials comprising dendrimers such as polyamidoamine (PAMAM), PAMAM (EDA), and polylysine dendrimers have been reported to have a significant antiviral effect against enveloped viruses, including the human immunodeficiency virus [144]. Anionic dendrimers including hydroxyl, carboxyl, and succinic-acid terminated PAMAM and cationic dendrimers containing primary amine end groups exhibit significant antiviral activity with MERS-CoV [145]. Nontoxic nanogel based polyglycerol sulfate dendrimer showed extensive antiviral activities by inhibiting viruses from binding to the cellular surfaces. Heparan sulfate also acts as a co-receptor for SARS-CoV-2 mediating entry to host cells. Therefore, nanogel based dendrimers could be a potential component in COVID-19 therapy [146, 147].
Polymeric Nanoparticles
Metal-based NPs have a higher surface area, enhancing the exclusive physicochemical properties that allow them to intermingle with viruses and other micro-organisms. The function of metal-based nanoparticles antivirals includes three interacting stages, (a) linking and connecting with the virus to inhibit the virus attachment penetration into the cell; (b) generating highly active oxygen, other ions and radicals that adhere to the wall (spikes or membrane) and able to destroy the structure and its function of viral proteins and nucleic acids; (c) simulating the nucleus to enhance the immune response of the host cell, and preventing the virus’s budding and spreading.
Silver–Based Antiviral Nanoparticles
Silver and its derivatives are classic antimicrobial compounds and in high demand for their impressive anti-pathogen performance. Silver nanoparticles (AgNPs) can interact with the outer layers of the virus and prevent their attachment on and penetration into the host cells. The average particle size of AgNPs is a crucial factor that affects their antiviral ability. Silver-based nanoparticles are classic anti-microbial compounds since they can work against pathogens efficiently. The average particle size of nanoparticles can affect their antiviral ability. They interact with the outer layers of the virus and prevent their attachment on and penetration into the host cells. Krzyzowska et al. [148] reported that Ag NPs could effectively control the herpes simplex virus type 2 (HSV-2) infection in mice by inhibiting the adhesion of the virus to host cells. Here, the silver nanoparticles quickly contact polioviruses (25–30 nm), destroy their proteins molecules, and prevent them from binding with the host cells. Han et al. [149] reported that for other silver nanoparticles (Ag2S), the antiviral activity is mainly ruled out by inhibiting RNA synthesis and viral budding. It was also argued that activating ISG proteins and pro-inflammatory cytokines might be an essential factor in this case.
Copper-Based Nanoparticles
Copper oxide nanoparticles are widely used to prepare antibacterial materials due to their low cost, higher stability, and wide range of antibacterial properties. The proposed mechanism by Tavakoli et al. [150] is as follows: the Cu2+ ions released from the nanoparticles enhances the formation of reactive oxygen species, which helps to collapse the HSV capsid integrity and degrade the whole genome. Also, nanoparticles of Cu2O having size (~ 50 nm) inhibits the HCV viruses to be attached to the cells through the multivalent binding of virions, thereby blocking the entry of the virus into the cell [151].
Gold-Based Nanoparticles
Gold nanoparticles (Au NPs) are biocompatible and possessing the ability to bind with biological ligands [152]. Generally, the mechanism of viral inhibition by Au NPs are based on blocking the viral particles to be bound to the cell, thereby inhibiting virus attachment/entry and controlling the cell to- cell spread of the virus. Studies show that morphologies of Au NPs have eater influence on antiviral properties and mechanisms [153,154,155].
Nanoparticles Applied to Viral RNA Extraction
Generally, extraction based on the column is not easy in automation. The advantage of this method is that the centrifugation is not included; therefore, it allows complete automated purification of nucleic acid, which was one of the parameters for SARS-CoV-2 diagnosis. Hence an automated extraction procedure was developed based on pcMNPs for viral RNA. A system consisting of magnetic rods was introduced for the purification of nucleic acid. An automated instrumental program was fixed as per the usual protocol. No further dissociation or removal of pcMNPs takes place in the extraction process even though the shaking speed of magnetic rods were at its maximum. The solution obtained was transparent and colorless. The method based on pcMNPs was highly advantageous and suitable, as discussed earlier in viral RNA extraction. The amplification curve of manually performed samples with direct RT-PCR was similar to positive control. The efficiency and working suitability of the pcMNPs-based method to identify and separate the nucleocapsid (N) gene originated. The outcomes proved again higher extraction efficiency of the automation method based on pcMNPs for manual and direct RT-PCR protocol with the help of ORFlab region and N gene assays.
The direct and straightforward RT-PCR protocols and N gene pseudovirus were compared with the modern and latest pcMNPs-based viral RNA process, which was more accurate and dynamic in the detection process. Standard fresh samples were prepared by 10-fold serial dilution to obtain copies of pseudovirus105–10in serum along with reference samples without pseudovirus, which can be used as a negative control to detect false-positive signals. The correlation coefficient (R2) was higher, about 0.999, between pseudovirus particle numbers (in logarithm) and cycle threshold (Ct) in the range of 10 to 105 copies. Similar results were also observed with experiments conducted by the direct RT-PCR method based on pcMNPs. The RT-PCR amplification is much more accurate for both with or without pcMNPs as per the resultant data. The amplification signals from negative control were less respectful to Ct but considered as valid positive results. Due to this drawback, it was mandatory to verify and optimize the primer pairs and probe. The PCR amplification and extraction efficiency were found better with the latest developed MB-based method. It concluded that RT-PCR assay even works more accurately with 10 copies of SARS-CoV-2 [156].
The biosensor based on nanoparticles (NBS) was combined with reverse transcription loop-mediated isothermal amplification (RT-LAMP), developed one step, and one tube RT-LAMP-NBS assay product for diagnosis COVID-19. The target sequences, F1ab and nucleoprotein gene (np), were amplified and identified in the test simultaneously with a constant temperature. It was necessary to optimize all the required parameters and their suitability to discuss the principle of RT-LAMP for COVID-19. The RT-LAMP-NBS assay was an almost equipment-free station, strengthening the laboratory system resources and reporting the results after diagnosis. RT-LAMP-NBS assay was low cost, feasible and sensitive for detection of SARS-CoV-2 [157]. So, it became a valuable diagnostic tool used in the field and a primary health care hospital. The design of COVID-19 diagnostics was the flexible modification of the existing diagnostic technologies.
The previous experience of the 2002 SARS outbreak made the researcher more cautious in taking the right decision, which enabled the diagnostics of this virus earlier. Its optimization process was quicker, which lead to a controlled spread of it. Furthermore, with the help of electron microscopy, the study of the virus became clearer. To design PCR primers and probes, the sequencing of the genome and the morphology of the virus were the required parameters. This technology was used to identify SARS-CoV-2 for less than one month, whereas the same detection took almost 5 months for SARS-CoV. Due to this technology, nucleic acid tests lead to the detection and sequencing of SARS-CoV-2. This type of action leads to control of the outbreak. Serological tests are the secondhand approach for testing this infection, which was more easily monitored than the nucleic acid test. Amplification at a constant temperature, barcoding, microfluidic technologies should be updated to be applied quickly for this situation. The latest technology of smartphones and diagnostics provides the highest surveillance and smooth communication of the latest updates. It was now clear that diagnostics were essential for reducing the mortality and further spread of pathogens [157]. The health worker dealt with diagnostic patients in different modes compared to others (Fig. 12).
Carbon‑Based Antiviral Materials
Carbon atoms can link to each other and form allotropes such as carbon dots, carbon nanotubes and graphene oxide. Here also the geometry of the carbon materials determines their anti-infection performance. Using carbon dots, Han et al. [158] demonstrated that the cells treated with CDs could stop the multiplication of pseudorabies virus (PRV) and respiratory syndrome virus (PRRSV) by the production of interferon-a (IFN-a) and IFN-stimulating genes (ISGs). Similarly, the GO and rGO [159] exhibited fascinating antiviral behaviours from their unique single-layer structure and surfaced negative charges. The negatively charged GO showed a higher potential to electrostatically interact with the viruses before entering the cell, ending in the destruction of its single-layer structure and sharp edges. However, the mechanism of antiviral activity in GO remains controversial.
Conclusion and Future Recommendations
Chitosan-based polymers and other polymeric materials such as CD, PEI, PLGA and PAMAM dendrimer have been used to treat and prevent infections caused by coronaviruses through inhibition of their replication. Following the recent outbreak of novel coronavirus (COVID-19), these polymers could be investigated as potential antiviral agents to treat this deadly virus as few have shown inhibitory effects. The natural and synthetic polymeric materials covered in this review are biocompatible, cost-effective, environmentally friendly, and much safer for antiviral applications, detection, and inhibition. On the other hand, nanoparticles mentioned in this review are used to detect and inhibit virus entry inside the host cell. This inhibition and detection properties of nanoparticles can be of interest for developing vaccines and treatments of COVID-19. It was observed that basic reproduction number, case fatality rate and incubation period are the most common factors in the epidemiology of several viral diseases that can be prevented by taking supportive treatment and preventive strategies without specific therapeutic intervention. However, it is now obvious that early detection is one of the best ways to break the spread of the virus until an effective and safe vaccine/medication or therapy is developed.
Currently, novel technologies and improvements in nanoscience can be used to detect and treat respiratory diseases caused by viruses. This review can be helpful and give insight into the upcoming studies for the development of nanomedicine against SARS-CoV-2 [160]. Moreover, the limitations caused by conventional and subunit vaccines can be solved by applying nanoparticles therapeutic approaches due to their unique nature, such as size, shape, surface area, and ability to functionalize, which causes strong immunogenicity and enhanced antigen presentation. The polymeric nanoparticle of Poly (lactic-co-glycolic acid) can be used in the human body without any side effect approved by the Food and Drug Administration [161]. As per the antibacterial and antifungal studies, inorganic nanoparticles based mainly on gold, silver, and zinc are among the best candidates for biomedical applications [106,107,108,109,110, 129,130,131, 162]. As per the data, the required conformational specific antibodies which are active to nullify the SARS-CoV infections via NPs-based systems were synthesized by the researchers [163]. Nowadays the researchers are actively monitoring peptide-based nanoparticles. The peptide inhibitor extracted from the protein ACE2 gives an extra edge for blocking SARS-CoV-2, whose binding efficiency can be increased with multiple binding of nanocarrier linked peptides [164]. But the toxicity of NPs should be carefully taken care of while designing the theragnostic NPs for respiratory diseases. Novel NPs reported reference to exhibit the following properties: easy penetration through the mucus membrane without sticking, biodegradable and less toxic, causing no lesions during treatment, easily modifiable chemical structure while adding surface capping agents.
From the previous studies for other types of viruses, nano-based vaccines have proven as a compelling candidate. Therefore, one of the future studies should be on the practical usage of polymeric nanoparticles as a drug/vaccine to develop long term immunization against coronaviruses. These nanomaterials may help in improving the sensitivity, detection limit, and analysis time of coronaviruses. Also, the potentiality of the electrochemical devices and techniques such as colorimetric sensing, electrochemiluminescence, immunosensing, electrochemical sensor, photoluminescence and chiroimmunosensing to find out the coronaviruses must be studied thoroughly.
