Plasma‐activated media (PAM) can be as effective as direct plasma treatment in killing cancer cells. PAM is produced by exposing liquid cell culture media to low temperature plasma. Reactive oxygen species (ROS) and reactive nitrogen species (RNS) in the aqueous state play key role in the anti‐tumor effects of PAM. The effectiveness of PAM is highly dependent upon the dose of reactive species. The...
The effect of a radio‐frequency driven, microscale non thermal atmospheric pressure plasma jet operated in helium with vol. 0.3% molecular oxygen gas admixture, on PC‐3 prostate cancer cells has been investigated. The viability of cells exposed to the plasma was found to decrease with increasing plasma exposure time, with apoptosis through caspase and PARP cleavage being observed. High concentrations...
