FIG. 4. Effect of varying exposure time of plasma treatment on the viability of CCRF-CEM cells. The cell viability was determined using trypan blue exclusion assays, and the values are expressed as the mean percentage of total viable cells 6 standard deviation of three separate experiments. (a) Cell viability determined at 12 h postplasma treatment and (b) cell viability determined at 36 h postplasma treatment.
