Atmospheric pressure plasma jets (APPJs) are sources of biologically active oxygen and nitrogen species. OH radical is one of the most reactive of Reactive oxygen species and plays crucial role in plasma chemistry at atmospheric pressure. The OH is also the precursor of hydrogen peroxide (H2O2), a m...
