The Influence of Acids on the Activity of Water in Plasma
Scandinavian Journal of Clinical and Laboratory Investigation, 1970The activity of water in plasma is measured by a thermometric method before and after addition of acids. The water activity remains nearly constant when HCI is added, probably owing to binding of the added HCI. The ion-protein binding has been evaluated by adding salts, bases and other substances to plasma and HCI to purified human albumin.

Mechanism of Virus Inactivation by Cold Atmospheric-Pressure Plasma and Plasma-Activated Water [PDF]
Applied and Environmental Microbiology, 2018 Contamination with pathogenic and infectious viruses severely threatens human health and animal husbandry. Current methods for disinfection have different disadvantages, such as inconvenience and contamination of disinfection by-products (e.g., chlorine disinfection).

Mass production of plasma activated water by an atmospheric pressure plasma
Japanese Journal of Applied Physics, 2020Abstract We report on the mass production of plasma activated water (PAW) by a non-thermal atmospheric pressure plasma. As a non-thermal plasma source, we used planar dielectric barrier discharge (DBD) and two types cylindrical DBDs. The manufacturing characteristics of PAW were investigated for each DBD type. The

Contribution to the Chemistry of Plasma-Activated Water
Plasma Physics Reports, 2018Plasma-activated water (PAW) was prepared by exposure to nonthermal plasma produced by a positive dc corona discharge in a transient spark regime. The activation of water was performed in atmosphere of various surrounding gases (air, nitrogen, carbon dioxide, and argon).

Mathematical modelling of plasma activated water
2023When water is exposed to an atmospheric-pressure plasma, species dissolve in the water and plasma activated water (PAW) is formed. Such substances have numerous applications across many fields of science. The plasma species and their concentrations in PAW depend upon many factors, such as the discharge mechanism of the plasma reactor used, the exposure

Plasma-activated water (PAW) is a novel antimicrobial agent with negligible toxicity and environmental burden, holding promise as an alternative to chemical disinfectants and antibiotics. In practice, liquid disinfectants are often soaked with cotton materials before further use. Rich in reducing functional groups on the surface, cotton will inevitably

Atmospheric pressure plasma activation of water droplets
Journal of Physics D: Applied Physics, 2019Abstract Low temperature plasma treatment of water is being investigated due to its use in pollution abatement, wound treatment and agriculture. Plasma produced reactive oxygen and nitrogen species (RONS) are formed in the gas phase and solvate into the liquid.

Characterization of microbial inactivation using plasma activated water and plasma activated buffer
2017Plasma activated water (PAW) has been shown to be a promising surface decontamination technique. Antimicrobial effects of PAW have been attributed to reactive oxygen and reactive nitrogen species, which act as oxidizing agents and also contribute to the acidifying effect, causing the pH of water to drop.
