Time-dependent growth of titania nanotubes from sputtered titanium thin films for bio-application

Summary form only given. TiO2 nanotubes are biocompatible and many studies have been carried out for their biotechnological applications, especially in relation to drug carriers. The purpose of this study is to apply TiO2 film on the variety of metal substrates that could be used as biomaterials, and by forming various depth of nanotubes on the films, biocompatibility of the TiO2 nanotube and its ability as a carrier is applied to variety of materials according to various purposes. In this work, we present the fabrication of self-organized TiO2 nanotubes layer that was grown from flat and thin sputter-deposited titanium (Ti) films on Si (100) wafer.
