Biomimetic Green Synthesis and Characterization of Nanoparticles from Leave Extract of Lavatera cretica and Their Improving Glucose Bigotry


This study aims to examine the biosynthesis and characterization of silver nanoparticles using Lavatera cretica (LCAgNPs) leaf extract mixed with silver nitrate and improving their glucose bigotry. The biosynthesis was first confirmed by the color change from colorless (metal salt solution) to brown (nanoparticle colloidal dispersion). The occurrence of the nanoparticles was further ascertained by several physicochemical studies including UV–Vis spectroscopy, transmission electron microscopy (TEM), energy dispersive X-ray (EDX) tomography, Fourier transform-infrared spectroscopy (FTIR) and X-ray diffraction (XRD). The UV–Vis spectroscopy of LCAgNPs indicated the surface plasmon resonance signature of Ag NPs at around 440 nm. The TEM analysis revealed a well-dispersed sphere that varied in size from 5 to 24 nm. The EDX results established that Ag was the major element and others such as C, O and Cl were also present, which specified that the biomolecules coincided the AgNPs. The FT-IR spectroscopic study exhibited that the functional groups such as O–H, C–O, N–H, C–H and C=O were accountable for the synthesis of AgNPs. The XRD pattern represented the crystalline nature of metallic Ag. In this results, it could be clinched that the silver nitrate was reduced to silver nanoparticles of small size and high stability, which were devoid of impurities. Hence, this study has proved that L. cretica leaf is a good source for the synthesis of AgNPs and their improved glucose bigotry.
