Abstract

Cold atmospheric plasma (CAP) has recently emerged as possible treatment for opportunistic infections and cancer. CAP is composed of gas ions, superheated electrons, electric fields and reactive oxygen and nitrogen species (RONS). It can be directly applied to biological tissue because heat generation is low and has further the advantage that its reactive cocktail can be modulated by changing the composition of the feeding gas. CAP has shown to damage cell membranes with some selectivity towards bacterial membranes but its mechanism remains unclear, preventing further development of the technology.
