Biomedical Applications of Carbon Nanotubes - A Review

Abstract

Carbon nanotubes feature small single-layer carbon straws and large hexagonal lattices with sp2 configuration. A tube is formed when a graphene sheet is folded up into a cylindrical shape.  Carbon nanotubes have recently been employed in diagnostic and therapeutic applications. Tissue engineering, bioimaging, biosensing, and gene therapy are some of the biomedical uses of carbon nanotubes. The open ends of nanotubes allow access to the interior surface. Since CNTs have vast interior volumes and may be loaded with chemical and biological species, making them ideal for biosensing applications. Medicinal molecules can also be loaded with anti-cancer medications at the tube's end, allowing carbon nanotubes to be employed for therapeutic purposes. Many newly described improved CNT systems might be used in the future for their enormous promise in biology. The vast potential of carbon nanotubes in biomedical applications is highlighted in this paper, which also discusses future prospects for biomedical uses.
