Carbon Nanotubes Show Promise in Biomedicine

Carbon nanotubes (CNTs), those tiny cylindrical configurations of pure carbon that have been finding myriad applications in a wide variety of fields, have been the subject of headlines for well over a decade for their potential uses in biological research and medical treatment. Progress toward those goals has been slowed by questions about the safety of the tiny particles when injected directly into the body, where they can sometimes accumulate in certain organs with unknown long-term effects.
