Elimination of Biological Contaminations from Surfaces by Plasma Discharges: Chemical Sputtering

“…Those studies are, however, not easy to compare, because they were made with a variety of different germs, such as Escherichia coli, Geobacillus stearothermophilus, Bacillus atrophaeus, Deinococcus radiodurans, and different plasma systems. Furthermore, the utilized reactors differ in their geometry, in the type of plasma excitation such as DC, [31] RF, [20,[32][33][34][35] or MW [36][37][38] as well as in the employed operational parameters. In some experiments the objects to be treated are placed in the active discharge, others use the plasma afterglow.…”

Cold atmospheric plasma manipulation of proteins in food systems

“…Despite the extensive research on the inactivation of microorganisms by cold plasma and their large-scale applications in biomedical sectors (Soloshenko et al, 2000;Moisan et al, 2001 and, the studies on the inactivation of enzymes by using cold plasma are still limited to the small or lab-scale. Most of these studies have been performed under simplified conditions in a buffer environment.…”

Destructive effect of atmospheric pressure pulsed corona discharge plasma in air on biofilms of opportunistic bacteria

“…In fact, corona discharge is a source of electromagnetic radiation, mainly in the ultraviolet region [29,30]. And at low pressure UV radiation in the wavelength range from 160 to 220 nm plays the main role in the sterilization of surfaces [31] However, in the case of atmospheric pressure plasma source such as the developed gas discharge device UV contribution into inactivation of bacteria is negligible [32]. This can be evidently explained by intensive absorbing shortwave length radiation by the ambient air.…”
