Research for Multi-purpose Atmospheric Pressure Plasma Device By Controlling Ion and Radical

Abstract

Atmospheric pressure plasma (APP) not only industrial fields but also the application to the medicine fields is expected. However, the empirical fact is early to the commercialization of the plasma medical equipment, and the healing mechanism to living tissue has a lot of uncertain points. Generally, the ions and radicals might have been generated by the rolling atmosphere in the APP flow. From the above-mentioned background, we are accomplishing the research on the development of the APP device to control the ion and radical selectively.As a result by the measurement of H2O2 and NO2 concentrations in distilled water treated by APP flow with simplified analysis instrument for water, H2O2 tended to increase while NO2 decreased when gas flow rate was increased was clarified. It was confirmed to be able to control the plasma products such as reactive oxygen and nitrogen species (ROS and RNS) by controlling the plasma parameter.
