| dc.description.abstract | In recent years, cold atmospheric plasma (CAP) has shown potential for
applications in the medical field, although the mechanism of action has not been fully
apprehended. To facilitate future research, it is necessary to develop a stable and flexible
cold plasma supply system to meet various experimental needs. In this study, a cold plasma
system was constructed based on the plasma jet method. An experiment was then
conducted on L929 murine fibroblast cells to evaluate the performance of the system and
to demonstrate the impact of CAP on cell proliferation. Analysis of experimental results
on L929 murine fibroblasts indicated that treatment with a cold plasma system resulted in
increased cell proliferation rates. The best proliferation effect was observed after 3
treatments. However, treatment results tended to decrease when the duration was extended
to 30 seconds. These findings suggest that, with an appropriate treatment time, CAP can
stimulate cell proliferation, but prolonged treatment times and frequencies may have the
