Abstract
In the recent era, nanomaterials (NMs) have been found useful for sensing as well as detection of several biomarkers, and these strategies are likely to develop point of care (PoC) diagnostics, which can be used for early disease detection and various therapeutic applications. Application of NMs in biosensing also allows the use of many novel signal transduction technologies in their preparation. The use of high surface area of NMs plays a crucial role in developing nanobiosensors. These nanoscale structures may include nanoparticles (NPs), nanotubes, nanorods, nanofibers, and thin films. Nanobiosensors have greater sensitivity, selectivity, and fast response time. Biosensing technologies include various types of techniques, viz., electrochemical, amperometric, voltametric, fluorescence, etc. Particularly, fluorescence-based sensing technologies possess many advantages in their detection, viz., simple instrumentation, less background signals or noise, and having potential for multiplexed analysis. Similarly, colorimetric sensors have been well-known for their naked eye visualization, simplicity, and cost-effectiveness features. This chapter describes the advancements in promising NMs which are aimed for on-site clinical applications and those which can be used as a personalized diagnostic device in different disease conditions.
