Carbon Nanotubes

Carbon nanotubes are one of the most promising Nanobiotechnology developed in the 21st century. They are cylindrical nanostructures of carbon atoms with unique physical and chemical properties. The most common form of carbon nanotube is single-walled carbon nanotubes (SWCNTs) which are composed of one concentric layer of carbon atoms arranged in a hexagonal pattern. The walls of carbon nanotubes are typically between 0.7 and 2 nanometers in diameter, but can be up to 50 nanometers in diameter. Due to their unique structure, carbon nanotubes have a number of desirable properties. For example, they have extremely high strength and stiffness, making them useful in a variety of applications. They are also highly conductive, both thermally and electrically, making them well suited for use in electronic components. In addition, carbon nanotubes have excellent chemical stability and can be used in a wide range of chemical reactions. The surfaces of these nanotubes can be functionalized to allow for the attachment of various molecules, making them useful for a variety of applications such as drug delivery and sensing.
