...Nathan Swami; Zhanwu Cui; Lakshmi S. Nair Nanostructured one dimensional titanium oxides such as nanotubes and nanowires have raised interest lately due to their unique electronic and optical properties. These materials also have shown significant potential as biomaterials because of their ability...
