Miniature Dielectric Barrier Discharge Nonthermal Plasma Induces Apoptosis in Lung Cancer Cells and Inhibits Cell Migration

Figure 4

Effect of plasma on detachment of lung cancer cells. (a) Cells were treated for 15, 30, 60, and 120 sec. Except for the control, all images are stitched images of multiple pictures. (b) Zoomed image of a portion of plates treated for 120 sec showing the formation of three zones. (c) The clearance zone area expressed as a function of treatment time. Scale bars are 200 μm. Data are means of the area (mm²) ± SD of three independent experiments run in triplicate. , , and denote statistically significant differences for 15, 30, 60, and 120 sec treatments, respectively ().
