Antibacterial properties of nanostructured Cu-TiO surfaces for dental implants.

The influence of copper derived TiO surfaces (nCu-nT-TiO) on the death of nosocomial Staphylococcus aureus (Sa) and Escherichia coli (Ec), was investigated. TiO nanotube (nT-TiO) arrays were fabricated by anodic oxidation of pure titanium sheets in fluorhydric solutions, leading to surface nanostructuration and creation of specific reactive sites. Copper nanocubes with a mean size of 20 nm have been synthesized and deposited on the nT-TiO surface by pulsed electrodeposition from a copper sulphate solution.
