The main focus of the review is to discuss about the most popular, expanding and promising branch of science and technology i.e., nanotechnology, its various applications in life sciences which opened up doors in several areas like diagnostics, drug delivery and tissue engineering. Nanotechnology is often viewed as a relatively young field, with tremendous potential to reinvent existing industries and significantly improve standards of living. Nanotechnology applications to the life sciences include pharmaceuticals, biotechnology, medical devices, diagnostics, gene therapy, drug delivery and tissue engineering.
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.
