Susceptibility of Staphylococcus epidermidis to Argon Cold Plasma Jet by Oxygen Admixture

Cold atmospheric pressure sterilization is one of the nominated and efficient techniques to prevent spread diseases. Reactive species such as O OH other radicals play a major role in mechanism plasma sterilization. Therefore, this work, oxygen was mixed with different parentage from (0.2 1.2%) argon enhance generation reactive increase efficacy. The emission spectra jet radicle line intensities by increasing percentage admixture O2 gas reach maximum power at 0.8; then, it gradually decreases higher percentage. band intensity O2. percentages tested against Gram-positive S. epidermidis, which causal agent nosocomial infections. reduction colony-forming units (CFU) observed 0.2% No bacterial growth later concentration applied for 8 min same case detected 0.4% 16 min.
