Reactive Oxygen and Nitrogen Species Production and Delivery Into Liquid Media by Microsecond Thermal Spark-Discharge Plasma Jet

The microsecond spark discharge plasma jet is experimentally analyzed, experimentally and numerical modeling is performed. It is shown that discharge appears as a the number of microdischarges resulting in the average gas temperature of the jet of about 40 degrees C-50 degrees C. Fast imaging and numerical modeling are performed in order to study the discharge development on both microsecond and nanosecond time scales. The biochemical study of the production and the delivery of reactive oxygen and nitrogen species (H2O2, NO, O-2(-), singlet oxygen, and ONOO-) into liquid phase is performed using fluorescent dyes.
