Novel plasma-based technologies that offer maximum efficiency at minimal environmental costs are expected to further promote the sustainable societal and economic development. Unique transfer of chemical reactivity energy from gaseous plasmas water takes place in absence any other chemicals, but results a product with notable transient broad-spectrum biological activity, referred as plasma-activated (PAW). These features make PAW green prospective solution for wide range biotechnology...

ABSTRACT Atmospheric cold plasma (ACP) is a promising nonthermal technology effective against wide range of pathogenic microorganisms. Reactive oxygen species (ROS) play crucial inactivation role when air or other oxygen-containing gases are used. With strong oxidative stress, cells can be damaged by lipid peroxidation, enzyme inactivation, and DNA cleavage. Identification ROS an understanding their important for advancing ACP applications complex microbiological issues. In this study, the...
