Abstract

Abstract: Reactive oxygen and nitrogen species (RONS) can be generated in liquids by different cold plasma processes. These species can influence cell biology and pathological states, and trigger wound healing, disinfection, and cancer treatments. The optimization of plasma sources' configurations and experimental conditions is fundamental to dose‐produced RONS in liquids. This research is a case study comparing RONS generation (H2 O2 and NO2 − ) in water, after exposure to two different atmospheric pressure cold dielectric barrier discharge (DBD) plasma sources: a plasma jet‐DBD and a planar‐DBD operating in contact with the liquid and in remote, respectively. The data demonstrate that the reactor geometry and the treatment modality strongly impact the generation of the active species in water. Abstract : Plasma treatment optimization is a key step to control the synthesis of reactive oxygen and nitrogen species (RONS) in liquids. This is a case study of the generation of H2 O2 and NO2 − in water after exposure to two atmospheric pressure dielectric barrier discharge sources. The main aim is to identify key factors that have involvement in RONS production and to foster the choice of properly designed plasma sources with attention to the final application.
