Abstract

Plasma jets, crucial atmospheric pressure sources in biomedical applications,generate reactive species in liquids, with electrical fields playing a significantrole, as variations in pulse rise times and durations in dielectric barrierdischarges yield diverse effects. This study presents a novel nanosecondpulse plasma jet. Here, investigations with phosphate‐buffered saline andRinger's saline elucidate critical parameters influencing species generation,such as treatment time and gas flow rate. Results showed increasingconcentrations of H 2 O 2 and NO 2− over time, with NO 2− degrading faster inRinger's saline due to acidifi-cation. The nanosecond pulsejet exhibits superior energyefficiency than conventionaljets, laying the groundworkfor optimizing species gener-ation and studying electricalfield effects in future biologi-cal works.
