Surface and Hand Disinfection Using Atmospheric Plasma Sources

Published: Aug. 30, 2023

Good hand hygiene has proven to be essential in reducing the uncontrolled spread of human pathogens. Cold atmospheric plasma (CAP) may provide an alternative disinfecting hands with ethanol-based handrubs when washing facilities are unavailable. CAP can safely applied skin if energy is well controlled. In this study, RF and DC sources was built a pin-to-mesh electrodes configuration inside fused silica tube 5 mm inner diameter. Microbiological assays based on EN 13697:2015+A1:2019 using Escherichia coli DSM 682 or Staphylococcus epidermidis 20044 were used examine antimicrobial effect various conditions. Metal silicone disks that model as inoculation matrices. The prototype air radio frequency (RF) achieved significant disinfection MHz range stainless steel substrates. This equivalent half performance direct current CAP, which only effective conductive Using electricity could, further optimization, replace complement methods, mitigate economic burden public health crises future.
