Schematic diagram showing the two methods of plasma treatment. (a) Direct treatment on cells with media and also depicts the general plasma generation process. Helium gas acts as a carrier gas for continuous generation of plasma (green line). Plasma (blue line) is generated in between the two electrodes by the application of high voltage. The generated plasma jet can directly be exposed to the cell culture vessels; (b) Exposure of cells into plasma treated media. (Dulbecco’s Modified Eagles Medium (DMEM) is cell culture medium used in conjugation with Fetal Bovine Serum (FBS)).
