Numerical modelling of plasmachemistry induced by cold atmospheric plasma jet near surface

Abstract

Abstract Recently the cold plasma jets are widely used for the development of anticancer therapy. The main mechanism of atmospheric plasma jet action on cells is related to the production of nitrogen and oxygen radicals in plasma-stimulated chemical reactions, followed by the diffusion of radicals into the media with cells. The increase of the plasma jet treatment efficiency depends on a detailed study of the plasma-chemical processes that occur when the plasma jet interacts with the target. In this work, a numerical study of the plasma-chemical processes for dry air is carried out, the main ways of production and loss of RONS are detected and mixture composition near the surface during plasma jet processing is estimated.
