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 electronic energy. Electronic can be moved from the conduction to the valence bands. At the same time, the holes in the conduction spectrum, which are responsible for generating electronic holes, also become electronic. A series of reactions occurs: adsorption and capture of O2, superoxide anion radicals reaction with the majority of organic matter, as well as the generation of electronic form O2. 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.

Nano titanium dioxide

has antibacterial qualities

The antibacterial qualities of nano titanium dioxide are: non-toxic and safe for human skin; Antibacterial strength, wide range; Low odor; Easy to clean; Durable storage; High thermal stability; Does not decompose at high temperatures; Nano titanium dioxide has a good immediate effect. Silver antibacterial agents require about 24 hours. Antibacterial agents such as nano titanium dioxide are able to maintain their antibacterial effects for life. This antibacterial agent is food-safe and doesn’t cause skin irritation.
