Plasma‐activated ethanol solution and it's decontamination effect

Abstract Ethanol solution as a disinfectant has been widely used in various fields. However, it significant bactericidal capability only when the volume fraction of ethanol is around 70%–75%. For such high concentration solution, an irritating smell. When for applications wound disinfection, causes stinging sensation. Low concentrations are less irritating, but also effective at killing bacteria. In this study, idea producing green, efficient and proposed. It based on plasma‐activated low‐concentration (PAES). found that 10% can kill more than seven orders magnitude Escherichia coli , while untreated no effect. Besides, PAES's activity remains unchanged after being stored three days. Further investigation shows new compositions including peracetic acid, peroxynitrite, hydrogen peroxide acetic acid detected PAES, which together playing main role excellent prolonged
