Morphology and metabolic activity of B ₁₆ F ₁₀ cancer cells after incubated with PAW. Microscopic image of shape and concentration of cells after treated with (a) 0 min (b) 2 min, (c) 4 min, and (d) 6 min of plasma-activated waters after 24 h incubation. (e) metabolic activity of melanoma cancer cells after 24 h. Data are presented as mean ± SD (n = 3).
