Synthesis of TiO2 nanopore arrays by pulsed laser treatment and anodic oxidation

The results show that the consecutive use of both processes allows changing the topological pattern thus developing a micro-nano topography that could selectively promote tissue cell attachment. While laser texturing promotes an important increase in the roughness due to the generation of dimples on the surface, the anodizing process fabricates a homogeneous nanoporous titanium oxide layer that it turns the surface hydrophilic. Moreover, corrosion resistance of the laser textured surface can also be improved due to the better chemical stability of the nanostructured oxide layer formed on the surface.
