Abstract (en):  hide
The main objective of this bachelor thesis was to experimentally test the effects of plasma activated medium (PAM) on non-cancer and cancer cells in vitro. We worked with human epithelial melanoma cells – A375 and human embryonic epithelial kidney cells – HEK293T and we used two types of cold atmospheric plasma discharges – streamer corona (SC) and transient spark (TS) with two different exposure times (0.5 min/ml and 2 min/ml) to activate the medium. We applied the PAM on cells 2 hours after its exposure to the plasma. We investigated the effects of PAM on cells by metabolic MTT assay and we studied microscopic changes of confluence, size and shape of cells using optical microscopy. We measured the specific absorbance of our samples, which we then used to calculate viability of cells. The measurements were done 24 hours and 72 hours after the application of PAM on cells.
