ZnO　and　Ag-containing　ZnO　(ZnO/Ag)　films　with　the　Ag/Zn　molar　ratio　of　3.3　and　9.1%,　respectively　were　sol-gel　coated　on　biomedical　titanium　for　antibacterial　and　bioactive　surface　modification.　X-ray　diffraction　analysis　indicates　that　ZnO　peaks　increase　with　the　calcination　temperature　of　the　samples.　Scanning　electron　microscopy　and　energy　dispersive　of　X-ray　analyses　reveal　Ag-rich　white　particles　(300　similar　to　750　nm)　on　ZnO/Ag　samples　that　were　calcined　at　400　degrees　C.　X-ray　photoelectron　spectroscopy　analysis　of　ZnO/Ag　samples　shows　that　Zn　and　O　exist　as　ZnO　and　Ag　presents　in　metallic　state.　The　coating　samples　exhibit　similar　UV　light-induced　hydrophilic　conversion　behavior.　Potentiodynamic　polarization　test　in　a　Ca-free　Hank＇s　balanced　solution　demonstrates　better　corrosion　resistance　of　the　coating　samples　compared　with　the　polished　sample.　In　the　in　vitro　bioactivity　test　using　the　simulated　body　fluid,　a　layer　of　apatite　is　gradually　deposited　on　the　surface　of　sample　ZnO/9Ag　after　12　days　of　soaking.　The　MTT　assay　test　shows　that　ZnO　and　ZnO/Ag　films　have　weak　compatibility　with　the　L929　cells.　The　antibacterial　test　against　E.　Coli　by　the　disk　diffusion　assay　reveals　that　antibacterial　activity　of　the　coating　samples　increases　with　silver　content　of　the　films.
