SUMMARY Atmospheric-pressure, nonthermal plasma jets produced by using helium gas have been studied for various applications. In particular, plasma applications for biological treatment have attracted attention and investigation all over the world. In this paper, various kinds of cell culture media were irradiated with a plasma jet, and its components were analyzed. The results showed that irradiating a cell culture medium with a plasma jet could cause changes in its pH, electrical conductivity, and so on. These results suggest that irradiating with a plasma jet might cause changes in the form of cells and produce cell death. Plasma jets also generate UV light, which may kill cells. It was found that the plasma jet irradiation time is a very important factor in the treatment of cells. [ABSTRACT FROM AUTHOR]
