Abstract
An augmented ceramic composite including aluminosilicate nanotubes may be added to a biocompatible polymer matrix. Aluminosilicate nanotubes have a surprisingly high biocompatibility, radio opaqueness, and suitability for storing therapeutic compounds for release over time. These surprising advantages make aluminosilicate nanotubes, such as halloysite nanotubes, a good candidate for use in various medical applications from bone and dental prosthetics to cancer treatment and prevention. Furthermore, unlike other additives, the addition of certain quantities of halloysite nanotubes increases the strength of the polymer matrix to which it is added.
