Carbon Nanotubes Have Room for Multifunctionality

In the quest to turn carbon nanotubes from nanoscale wonder into clinically useful drug and imaging agent delivery agents, researchers have often added polymer coatings to the outside of the nanotubes in order to render them biocompatible. Now, researchers at Stanford University have found that even when coated, carbon nanotubes retain the ability to bind extraordinarily large numbers of drug and imaging agent molecules in a stable yet reversible manner.
