Nanotubes in biological applications

Abstract

Researchers over the last few years have recognized carbon nanotubes (CNTs) as promising materials for a number of biological applications. CNTs are increasingly being explored as potent drug carriers for cancer treatment, for biosensing, and as scaffolds for stem cell culture. Moreover, the integration of CNTs with proteins has led to the development of functional nanocomposites with antimicrobial properties. This review aims at understanding the critical role of CNTs in biological applications with a particular emphasis on more recent studies.
