Overview of Carbon Nanotubes and Their Biomedical Applications

Carbon nanotubes, often known as rolled-up graphene sheets, are cylindrical nanostructures composed of carbon atoms organized in a hexagonal lattice. One of the most fascinating discoveries in the field of nanoscale sciences is carbon nanotubes, or CNTs. They can have graphene arranged in one or more layers (multi-walled carbon nanotubes, or MWCNTs) or in a single layer (single-walled carbon nanotubes, or SWCNTs). Because of their remarkable mechanical strength, electrical conductivity, and thermal characteristics, CNTs are useful in a variety of applications. Applications for carbon nanotubes in biomedical include tissue engineering, gene therapy, and targeted medication delivery, among others. Several methods, including as chemical vapor deposition, laser ablation, arc discharge, and laser ablation, have been devised to create nanotubes in significant quantities. The study's focus on carbon nanotubes is on their kinds, characteristics, production processes, benefits and drawbacks, and biomedical applications.
