The key to cuprous oxide, the aspect that makes is extremely effective as a biocide, is that active state. It is still producing reactive oxygen species, highly reactive molecules. These are unstable molecules that cause damage to cell structures.
Copper (I) oxide nanomaterial Cuprous oxide nanoparticles can react with sulfhydryl and disulfide bonds in the compounds to produce corresponding sulfhydryl copper compounds.The mercapto and disulfide bonds play a key role in the normal life of microorganisms.Therefore, cuprous oxide nanoparticles can interfere with the biochemical reactions of microorganisms, further interfere with their physiological activities, and even induce their apoptosis.In addition, cuprous oxide also has a strong adsorption effect, which can be adsorbed on the cell wall of bacteria and destroy the cell wall and cell membrane, resulting in the death of bacteria.
Using 30-50nm cuprous oxide nanoparticles and staphylococcus aureus (S,a) as the model, the researchers found that cuprous oxide nanoparticles at concentrations of 5 and 10ug/ml had a bacteriostatic rate of 71.8% and 96.6%, showing good bacteriostatic activity.In addition, it also has a killing effect on gram-negative bacteria.Nano cu2o-tio2 composite can induce the apoptosis of human cervical cancer cells.
Cuprous oxide nanoparticles can also be used as highly effective pesticides.Used as antifouling primer for ships to prevent Marine life from attaching to the bottom of ships
