Concentration of hydrogen peroxide and nitrites revealed in the PALM in three different experimental conditions: Air 1 min (0.5 slm Air, 13 kV, 1 min, 100 msT, 50% DC); O2 1 min (0.5 slm O2, 13 kV, 1 min, 100 ms of period T, 50% DC); and O2 3 min (0.5 slm O2, 13 kV, 3 min, 100 msT, 50% DC). Photos: pictures corresponding to a PALM solution obtained from the three different plasma conditions and treated with the H2O2 kit. *Control: untreated cell culture treated with the H2O2 kit.
