Fig 1

(A) Cold atmospheric plasma (CAP) jet, with which can be mounted for treatment directly over culture plate containing various glioma cell lines (U87, U373, A172) for various durations. (B) The parameters of the CAP were an output voltage between 4.5–5 kV, a frequency of 13 kHz and a helium flow rate at 10 L/min. The distance between the jet and the base of the culture plate was maintained at 20 mm, yielding an average jet dose of 0.8 J/sec/cm2.
