Stress response ofEscherichia coliinduced by surface streamer discharge in humid air

Reactive species responsible for the inactivation of feline calicivirus by a two‐dimensional array of integrated coaxial microhollow dielectric barrier discharges in air

“…Under acidic conditions (pH < 3.5), nitrites NO À 2 À Á convert into nitrous acid (HNO 2 ) (see reaction [4]). HNO 2 can further decompose into NO⋅ and NO 2 ⋅ via reaction (5). These radicals are known to possess strong cytotoxic attributes under acidic conditions and are more commonly known as acidified nitrites.…”

“…Additional complexities arise because of the inability to compare results between different research teams due to the use of a wide variety of plasma devices and experimental conditions, which produce different species densities and fluxes. Some of these plasma sources include plasma jets, streamer discharges, gliding arc discharges, and dielectric barrier discharges (DBDs) . In view of the complexity of plasma‐bio interactions and the huge parameter space of plasma operating conditions, it is important to identify the reactive species responsible for the inactivation of bacteria and viruses by plasma.…”

“…Most of the reported studies on plasma‐bio interaction are geared toward bacteria, while only a limited literature is available describing the inactivation of viruses and the mechanisms leading to virus inactivation . Ozone produced by commercially available ozonizers is found to be effective against viruses in hospital wards and operation theaters .…”

“…The application of cold atmospheric pressure plasmas (CAPs) for bio-decontamination and disinfection has been widely studied and is emerging as a potential and highly effective alternative technology for non-thermal decontamination. [1][2][3][4][5][6][7] When generated in air, CAPs produce a cocktail of reactive oxygen and nitrogen species (RONS), including O 3 , O 2 (a 1 Δ g ), NO, NO 2 , HNO 3 , HNO 2 , ONOO − , H 2 O 2, and OH. [2,8] The complex interaction of these species with microbial agents makes it challenging to understand the detailed underlying inactivation mechanism.…”

“…Some of these plasma sources include plasma jets, streamer discharges, gliding arc discharges, and dielectric barrier discharges (DBDs). [1,5,[9][10][11] In view of the complexity of plasma-bio interactions and the huge parameter space of plasma operating conditions, it is important to identify the reactive species responsible for the inactivation of bacteria and viruses by plasma. An optimization of the production of these species based on basic principles will allow us to more fully exploit the potential of plasma-based decontamination.…”
