Experiment on inducing apoptosis of melanoma cells by micro-plasma jet

Abstract

As a promising cancer treatment method, cold atmospheric plasma has received widespread attention in recent years. However, previous research has focused more on how to realize and expand the anti-cancer scope of plasma jet. There are also studies on the killing of small-scale cancer cells, but the effects of plasma jet on normal cells and normal cell clusters have been ignored. Therefore, we proposed a 50 µm sized micro-plasma jet device, and used the device to treat melanoma cells (A-375) and human glial cells (HA1800) to evaluate their anti-cancer effects and effects on normal cells. The experimental results show that this kind of micro-plasma jet device can effectively inactivate cancer cells in a short period of time, while having little effect on normal cells. This work provides a certain experimental basis for the application of fine plasma jet to clinically inactivate cancer cells.
