Nanotubes for drug release: Titania nanotubes (see image) fabricated by an easy anodization process can be used as drug-eluting coatings for implantable devices. The release rate of the drugs is controlled by varying the amount of proteins loaded into the nanotubes. Moreover, by changing the nanotube diameter, wall thickness, and length, the release kinetics can be altered for each specific drug to achieve a sustained release.
