After a five-day microplasma treatment, the results displayed a significant decrease in the growth of U87 glioma cancer (brain tumor), compared to the control group where microplasma was not applied. GREMI performed further in vitro studies regarding U87 gliomal cancer (brain tumors) and HCT116 (colon tumor) cell lines where microplasma was applied. This microplasma treatment was proven to be an efficient method in destroying cancer cells after being applied over periods of a few tens of seconds.
