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

Figure 5

Live and dead cell count for treatment times 15, 30, 60, and 120 sec. (a) Detached live and dead cells immediately after the plasma treatment (day 0). (b) Detached live and dead cells 24 h after the plasma treatment (day 1). (c) Total number of attached dead cells on day 1. Data are expressed as mean of cell number ± SD (). , , and , denote statistically significant differences between dead cells of control and 15, 30, 60, and 120 sec plasma treatments, respectively ().

(a) Detached cells analysis: day  0

(b) Detached cells analysis: day 1

(c) Attached cells analysis: day 1
