Revise: Properties and uses of nanoparticlesA carbon nanotube is a cylindrical fullerene with a very large length compared with its diameter. Its nanoscale diameter allows it to act as a molecular sieve: whether a particle can pass through depends on its size relative to the opening. Nanotubes may also be incorporated into other materials, producing strong, lightweight composites such as reinforced sports equipment.
