Study of the electrochmeical biosensor has become a new interdisciplinary frontier between biological detection and material science due to their excellent prospects for interfacing biological recognition events with electronic signal transduction. Nanomaterials provided a significant platform for designing a new generation of bioelectronic devices exhibiting novel functions due to their high surface-to-volume ratio, good stability, small dimension effect, good compatibility and strong adsorption ability. In this paper, we review the development of electrochemical biosensors fabricated with various nanoscale materials, also highlight the analytical applications in terms of biochemistry.
Nanomaterials include nanometal, nanooxide, carbon nanotube, carbon nanotube composite and other types of nanomaterials. They provide a significant way for the manufacture of sensors due to their small size, larger specific surface area, surface atomic slots insufficiency and more active sites. The rapid development of electrochemical sensor fabricated with nanomaterials is of significant value. In this article, we address some of the main advances in this field over the past few years, discussing the research progress of electrochemical sensor fabricated with nanomaterials and their application.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
