Advancement in Nanoparticle-based Biosensors for Point-of-care In vitro Diagnostics

Abstract

Abstract: Recently, there has been great progress in the field of extremely sensitive and precise de-tection of bioanalytes. The importance of the utilization of nanoparticles in biosensors has been rec-ognized due to their unique properties. Specifically, nanoparticles of gold, silver, and magnetic plus graphene, quantum dots, and nanotubes of carbon are being keenly considered for utilization within biosensors to detect nucleic acids, glucose, or pathogens (bacteria as well as a virus). Taking ad-vantage of nanoparticles, faster and sensitive biosensors can be developed. Here, we review the na-noparticles' contribution to the biosensors field and their potential applications.
