Nanosized surface topography on an implant material has the capability of stimulating the acceptance of the material in its host surrounding. Fine-tuning of nanotopography feature size has been shown to trigger differentiation of mesenchymal stem cells into bone cells in vitro. For this purpose we have created well defined nanosized titania dot- and pillar-like structures on mechanically polished Ti substrates using a through-mask anodization technique with an anodic porous alumina template. The anodization technique allowed the titania structure dimensions to be precisely tuned in the range 15-140 nm in a single electrolyte system. The fabricated surfaces serve as good model surfaces for precise studies of in vitro cell behaviour. The through-mask anodization technique was used directly on bulk Ti surfaces, thus demonstrating a potential application for patterning of actual Ti implant surfaces.
