Si-incorporated TiO 2 nanopores films were prepared by anodization and silicon plasma immersion ion implantation. The microstructure and phase composition of the films were investigated by scanning electron microscopy, X-ray diffraction and X-ray photoelectron spectroscopy. The hydrophilicity of the films was evaluated using water contact angle measurement and MG63 cells were cultured on the films to investigate the cytocompatibility. The results showed that the concentration and depth of silicon on the Si-incorporated TiO 2 nanopores films increased with the duration time of implantation. Both the as-annealed and Si-incorporated nanopores films exhibited good hydrophilicity and cytocompatibility, while the TiO 2 nanopores films implanted silicon for 1.0 h showed higher proliferation rate and vitality of MG63 cells than others, indicating a great potential application for titanium implants.
