The antibacterial effects of nanometer-sized titanium dioxide
To achieve an antibacterial effect, nanometer titanium dioxide is used in photocatalytic degradation of bacteria. Nano-titanium dioxide’s electronic structure is characterised by an electronic band with a tio2-filled and empty conduction bands. It can be irradiated using sunlight or ultraviolet light to increase the band gap energy. Electronic can be moved from the valence bands to the conduction, and at the same moment the holes in that valence area, which are responsible for generating electronic holes, is also generated by the electric field. A series reaction occurs: adsorption or superoxide anion free radicals reactions with almost all organic matter, including oxygen. The hole can react with organic material in bacteria to create CO2 and water. This hole converts the OH and H2O that are adsorbed to TiO2 onto OH. Strong oxidation power, *OH attacks unsaturated organic bonds or extracts H-atoms to produce new free radicals.
