SilverAg Nanoparticle /Nanopowder CAS Number : 7440-22-4
This product is antibacterial socks containing silver nanoparticles. Silver concentration in the product is less than 2 ppm. It also shows a remarkable antibacterial activity. In nano-dimension, antibacterial effect of silver increases significantly, so that they are able to destroy over 650 bacterial species. With decreasing particle size, the release of silver ions increases, leading to increasing their antibacterial activities. It is reported that these nanoparticles have significant antifungal activities against some ringworms. Ag nanoparticles interact with sulfur and phosphorus compounds of membrane proteins affecting cell morphology and structure, causing its death.
With growth in world population and the spread of disease, the number of antibiotic resistant microorganisms is rising along with the occurrence of infections from these microorganisms. With this increase in health awareness, many people focused their attention on educating and protecting themselves against harmful pathogens. It soon became more important for antimicrobially finished textiles to protect the wearer from bacteria than it was to simply protect the garment from fiber degradation. The need for antimicrobial textiles goes hand-in-hand with the rise in resistant strains of microorganisms. Silver ions and compounds are highly toxic for a wide range of bacteria and they show very low toxicity for human cells. So that, the use of silver in different forms has been a common method for antibacterial protection. It is important to remark that the antibacterial effect of polymer-silver nanocomposit is preserved and good antibacterial efficiency against a wide variety of bacteria is observed.
