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

Figure 6

Optical and fluorescence stitched images 24 h after plasma treatment for 15, 30, 60, and 120 sec to determine cell viability. The stitched images visualize the whole treated area. Control images were taken before plasma treatment. Green is live cells. Red is dead cells. Scale bars are 200 μm.
