Abstract
The purpose of this study was to verify the modifying effect of cold plasma on the dielectric permittivity of human skin samples. We fixed the shifts of dielectric properties of human skin specimens, which were specific for processing by non-ionized inert gases (argon and helium) and cold plasma. The dielectric permittivity of tissues was estimated using near-field resonant microwave sensing. It is established that the treatment of fragments of biological tissue (human skin) with the considered flows of non-ionized and ionized inert gases (helium and argon) has a significant effect on the dielectric characteristics of this biological object. At the same time, the identified effects are specific for each of these effects. Argon and argon cold plasma reduce the dielectric permittivity of the skin sample, and to a greater extent – non-ionized gas (on 24.3%). On the contrary, helium causes an increase in the studied parameter, but only in the form of cold plasma. This indicates the unequal influence of the considered physical factors on the morphological structure of the biological sample.
