How the Zinc Oxide Nanopowders Antibacterial?
Zinc oxide nanopowders antibacterial mechanism is base on the mechanism of metal ion dissolution. The free zinc ions with redox, and can react with organic matter like thio, carboxyl, hydroxyl ect. Then combine with the bacterial cell membrane and membrane protein to destroy its structure and make it loss of activity, to achieve the purpose of anti-bacterial. Zinc oxide powder antibacterial ability is related to the number of holes on its surface. When the surface has lots of holes will create a lot of electrons. At the same time the vacancy can also participate in the reaction directly could improve the bactericidal performance.

For the Zinc oxide nanopowder reach the nano size could have much better bactericidal performance compare to the traditional antibacterial effect of ZnO. For the nano ZnO antibacterial mechanism refer to photocatalysis. For nano ZnO has the specific surface effect of nano-particles, can increase the affinity of ZnO and bacteria, improve the antibacterial efficiency. Under ultraviolet light, the electrons in the valence band are excited to the conduction band, forming a freely moving electron (e-) and a positively charged hole (h +), which could activate the oxygen in the water and air. For the reactive oxygen with strong chemical can react with the organic matter of bacteria to kill bacteria. For nano ZnO antibacterial with two mechanisms greatly enhance the antibacterial ability. The smaller article size of ZnO will have stronger antimicrobial ability.
