“…Plasma has been used for decades to sterilize surfaces, 1,2 and argon plasma coagulator (APC) techniques are widely used to cut or ablate tissue and to coagulate bleeds. 3 These surgical devices typically function by supplying localized delivery of radio frequency (RF) energy to a focused point to produce the desired clinical effect through thermal means. The relatively recent discovery of cold atmospheric plasma (CAP) has sparked the creation of a range of new devices that do not produce such dramatic thermal effects and instead operate by delivering a range of active species to the target site to provide a more subtle result.…”

An in vitro study was conducted to compare the interaction of two cold atmospheric plasma devices on mammalian cells. The two devices were powered by the same FDA-cleared radio frequency power supply, but operated under different power regimes-direct and afterglow. Cells were plasma-treated for various amounts of time, and cell counts were performed at 24 and 48 hours after treatment. Thermal and electrical analyses in combination with chemical analysis of peroxide, nitrites, nitrates, and pH were conducted to identify the long-lived interactions that could impact cell viability. Optical emission spectroscopy was used to monitor the short-lived plasma species generated by each method. It was found that both plasma modes gave rise to differences in the levels of active species generated and this impacted the cellular response.
