- Abstract
- Low temperature atmospheric pressure plasmas have been known to be effective for living cell inactivation in a liquid solution but it is not clear yet which species are key factors for the cell treatment. Using a global model, we elucidate the processes through which pH level in the solution is changed from neutral to acidic after plasma exposure and key components with pH and air variation. First, pH level in a liquid solution is changed by He+ and He(2(1)S) radicals. Second, O-3 density decreases as pH level in the solution decreases and air concentration decreases. It can be a method of removing O-3 that causes chest pain and damages lung tissue when the density is very high. H2O2, HO2, and NO radicals are found to be key factors for cell inactivation in the solution with pH and air variation. (C) 2012 American Institute of Physics. [http://dx.doi.org/10.1063/1.4739777]
