From: Synergistic Effect of H2O2 and NO2 in Cell Death Induced by Cold Atmospheric He Plasma
Percentage of viable cells after a He plasma treatment at a gas flow of 400 sccm.
MRC5Vi and HCT116 cells were exposed in PBS(Ca2+/Mg2+) to He plasma (direct treatment) or to plasma-activated PBS(Ca2+/Mg2+) (indirect treatment) for 1, 2, 4 and 8 min. The He flow was set to 400 sccm and the output voltage to 8 kV. The cell viability assay was performed 24 h post treatment. The red lines indicate the percentage of viable cells after 2 min of He plasma treatment. The data are the average ± SD of 4 independent experiments (t-test p > 0.05)
