Nano Copper oxide is a kind of brown black metal oxide powder, which has a wide application. In addition to the role of catalyst and sensor, an important role of nano copper oxide is antibacterial.
Although antibiotics can treat most bacterial infections, development of microbial resistance restricts the advantages of the antibacterial agents in controlling infectious diseases. This is a major challenge that poses a serious threat prompting the search for alternative strategies to treat bacterial infections.
The antibacterial process of copper oxide can be simply described as follows: under the light excitation of energy greater than the forbidden band width, the hole - electron pairs generated will interact with O2 and H2O in the environment, and the free radicals generated such as reactive oxygen species will have chemical reactions with organic molecules in cells, so as to decompose cells and achieve the purpose of antibacterial.CuO is a p-type semiconductor with holes (CuO) +, which may interact with the environment and play an antibacterial role.The results show that CuO has good bacteriostatic activity against various cariogenic bacteria, pneumonia and pseudomonas aeruginosa.
Adding nano copper oxide to plastics, synthetic fibers, adhesives and coatings keeps it active for a long time, even in harsh environments. Hwnanomaterial can provide antimicrobial CUO Copper Oxide nano powders and dispersion with particle size ranging from 20-50nm. welcome to inquiries.
