The aim of this work is to study the initial adsorption steps of strontium doped calcium phosphate compounds onto a nanostructured TiO2 surface and to evaluate its influence on the adsorption of Bovine Serum Albumin (BSA). TiO2 nanotubes (nT-TiO2) arrays were fabricated by anodic oxidation of titanium samples in a fluoride-based solution. Calcium phosphate (CaP) and Strontium doped calcium phosphate (Sr.CaP) have been deposited using pulsed electrodeposition process. Surface nanostructuration (nT-TiO2) allows the creation of specific reactive sites on TiO2 surfaces which are not existed on non-nanostructured ones. Scanning Electron Microscopy (SEM) reveals that the most reactive sites on these nanostructured surfaces for CaP adsorption were the nanotube edges where the CaP deposits mostly growth. Due its positive bioactive properties in inducing bone forma.. View More»
