Schematic of the experimental setup.
MCF-7 cells were stained with DAPI, and observed under fluorescence microscopy at a magnificence of ; arrows indicate apoptotic cells. The sample images observed in the pulsed Ar plasma jet with following different conditions: (a) nontreated control, (b) Ar with the 5 SCCM of oxygen gas, and (c) Ar with the 10 SCCM of oxygen gas.
Flow cytometric analysis using Annexin V and PI staining. The apoptosis stages (the upper figures) and the FITC fluorescence histogram (the bottom figures). The analysis was obtained in the He plasma jet with following different conditions: (a) nontreated control, (b) He only, and (c) He with the 5 SCCM of oxygen gas.
The increase rates in apoptosis and necrosis of cells after the exposure to plasma. With a flow cytometric analysis, the results after treatment of (a) the He plasma demonstrated a larger apoptotic rate than that of (b) the Ar plasma.
Optical emission spectra from 200 to 800 nm observed in (a) He and (b) Ar plasma jets.
