nano zinc oxide will be a novel type of fine, high-performance organic material for the 21st Century. About 1100nm is the particle size of n. Due to the small particle sizes, both the electronic structure as well as the crystal structure of ZnO has changed. These changes have resulted in macroscopic properties such quantum size effect or surface effect that are not available for macroscopic objects.
Sterilization and Disinfection Mechanism
1. The continuous release of zinc ions from nano zinc oxide in an aqueous media can cause the cell membrane to rupture. These zinc ions may also damage the protein structures and spatial organization of proteins and bacteria. This causes the protease in cells to activate and kill bacteria. Zink ions can be dissociated from bacteria after destruction and used to repeat sterilization.
2. Nanometers zinc oxide may interact with the surface cells of bacteria and destroy them.
3. Nano ZnO produces hole electron pairs. Electrons and holes are able to migrate through the conduction bands and valence bars of zinc oxide particles. Hydrogen or hydroxyl groups that have been adsorbed on the surface can be converted into hydroxylradicals. Adsorbed oxygen can then become reactive oxygen species. Both reactive oxygen species and hydrogen oxygen-free radicals are strong in chemical activity. They can be used to react with many organic compounds and kill the majority of bacteria and viruses. The nanometer particles of zinc oxide are too small in size, which reduces electrons and holes travel times from the conduction bands and valence to the crystal surface. Also, electron recombination probabilities are lower, so zinc oxide’s antibacterial properties with nanometer sizes is greater.
According to the experiments, the germicidal rate of Staphylococcus ausreus increases with an increase in the zinc oxide suspension concentration. The treatment time is also a factor that determines whether the germicidal effectiveness of this strain is greater than Escherichiacoli’s. It is evident that the nanometer zinc dioxide suspension exhibits germicidal efficiency.
Zinc Oxide Nanoparticles Uses
1. Manufacturing surgical clothes
The function of shielding UV radiation is achieved by nanometer zinc oxide, which can absorb and scatter ultraviolet light. Since nanometer zirconium oxide is a semiconductor with a band gap direct, it can be absorbed by ultraviolet radiation. The electrons of the valence bands are able to absorb energy from ultraviolet radiation. They then move on to the conduction. Once the transition is complete, holes electron pairs are produced and UV radiation will also become absorbed. The nanoparticles have the ability to scatter UV radiation in any direction, even if it is at a longer wavelength than nano-ZnO. A nanometer of zinc oxide can be sized from 1-100 nm to the UV wavelength. Nano-zinc oxide also has a better shielding ability for long-wave ultraviolet (wavelengths 320-400nm), and medium-wave violet (wavelengths 280-320nm). Nanometer zinc dioxide is safer than organic ultraviolet absorbers and more reliable. It can also be used for ultraviolet shielding and fiber materials. Nanometer zinc oxide VK-30, which is produced in our company, has a size of 30 nanometers and good dispersion in the medium.
2. It is used in dentistry
In early dental treatments, the weak strength of composite resin often results in treatment failure. This is why a mix composite resin provides better performance. The nano-ZnO Crystal requires complete structure. There are almost no internal defects. They also have high strength and modulus. Because of its unique 3-D tetragonal shape, it can affect the mechanical properties. Therefore, adding this crystal to the composite resin system will significantly increase the mechanical characteristics of the resin. Because of its antibacterial qualities, nanometer zinc dioxide can also be used in dental resin to replace porcelain teeth.
