Interaction of low-temperature atmospheric pressure plasma jet mixed with argon and air with living tissues

Abstract

The paper presents the results of spectral-fluorescence and diffuse-optical studies of biological tissues when exposed to a low-temperature atmospheric pressure plasma in a mixture of air with argon with an exposure of up to 10 minutes. Potential fluorophores were identified and the coefficients of optical absorption and transport scattering of biological tissues were determined. The analysis conducted allows to conclude that plasma probing leads to significant inhibition of cellular respiration and the development of coagulation effects in biological tissues.

Investigation of Nonthermal Plasma Jet Excitation Mode and Optical Assessment of Its Electron Concentration

“…Sine SHF voltage is used to produce a plasma jet with low gas temperature at a low working gas flow rate (<1 L/min) [6]. Typically, SHF power supplies are bulky, expensive and inefficient.…”
