From: The Cell Activation Phenomena in the Cold Atmospheric Plasma Cancer Treatment
The demonstration of the existence of the activation state after the direct CAP treatment. The activation state of cells will significantly weaken the threshold of cancer cells to the cytotoxicity of H2O2. The “1 or 2 min CAP activation” means that a direct CAP treatment was performed on cancer cells in 96-well plate for 1 min or 2 min. The “15, 22, or 30 μM H2O2” means that a specific H2O2 concentration of H2O2-DMEM is used to affect the growth of the cancer cells with or without an activation. The data of Case 1, Case 2, Case 3, and Case 4 were shown in blue, orange, gray, and yellow, respectively. The protocols were illustrated in text. All experiments were performed in triplicate and were independently repeated for at least 3 times. The results were shown as the mean ± sd. Student’s t-tests were performed and the significance was indicated as ***p < 0.005, **p < 0.01, *p < 0.05, respectively.
