The minimum inhibitory concentrations (MICs) assays conducted for Escherichia coli, S Staphylococcus aureus, Bacillus subtilis, and Penicillium phoeniceum cultures have shown that the antimicrobial activity of silver ions was superior to that of silver nanoparticles. The efficacy of nanosilver as an antimicrobial agent has been estimated against a range of microbes on the surface of fibrous ion-exchange sorbents. The cytotoxicity of silver nanoparticles has been studied using NIH-3T3, HEP-G2, A-549, PC-12, and Colo-320 cells via the MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl-tetrazolium-bromide) test. The obtained MTT test results have shown that silver nanoparticles with concentrations of ~1–10 ppm entering the body from air or liquid suspensions can present a potential risk to human health. |
