Abstract: The resistance of bacterial strains to current antibiotics has become a serious public health problem which needs us to develop new bactericidal materials. As photocatalyst, nano-TiO2 materials have a safe and efficient antibacterial activity, which makes them more and more widely used in the field of antibacterial. This paper reviews the antibacterial mechanism and influencing factors of photocatalytic nano-titanium dioxide materials.

Key words: titanium oxides, photocatalysis, antibacterial mechanism, nanotechnology
