了解等离子体-液体相互作用对于生物医学以及更好地调整大气压等离子体射流 (APPJ) 在生物靶标上/内诱导的生物过程至关重要。为了研究相互作用的物理机制，当不同的工作气体 APPJ 撞击液体时，可以诊断放电可视化、电气特性、子弹动力学行为以及气相和液相中活性氧和氮物种 (RONS) 的产生。实验结果表明，He工作气体中添加少量的N2或O2会由于促进潘宁电离而显着改变射流羽流的形态并影响电流幅值。对于子弹传播来说，子弹的形状和速度表现出巨大的差异，并且可能强烈依赖于沉积在液体表面的表面电荷形成的电场；通过比较接触和不接触液体表面，撞击在水中的 APPJ 表明活性物质的发射强度较高，特别是由于水蒸气蒸发到等离子体中而导致的 OH 强度；对于液体中产生的水性 RONS（H2O2、NO3− 和 NO2−），我们发现 He + O2 APPJ 中产生的 H2O2 越多，He + N2 APPJ 中获得的 NO3− 和 NO2− 浓度就越高。此外，由于 HNO3 和 HNO2 形成浓度较高，由 He + N2 APPJ 激活的液体显示出最强的酸化效率。了解等离子体-液体相互作用对于生物医学以及更好地调整大气压等离子体射流 (APPJ) 在生物靶标上/内引起的生物过程具有重要意义。为了研究相互作用的物理机制，当不同的工作气体 APPJ 撞击液体时，可以诊断放电可视化、电气特性、子弹动力学行为以及气相和液相中活性氧和氮物种 (RONS) 的产生。实验结果表明，He工作气体中添加少量的N2或O2会由于促进潘宁电离而显着改变射流羽流的形态并影响电流幅值。对于子弹传播来说，子弹的形状和速度表现出巨大的差异，并且可能强烈依赖于沉积在液体表面的表面电荷形成的电场；通过比较触摸和不触摸液体表面，APP...
The understanding of plasma-liquid interactions is of major importance in biomedicine and to better adjust the biological processes induced on/in the biological target by atmospheric pressure plasma jets (APPJs). In order to investigate the physical mechanism of the interaction, the discharge visualization, electrical characteristics, the behavior of bullets dynamics, and the production of reactive oxygen and nitrogen species (RONS) in gas and liquid phases are diagnosed when different working gas APPJs are impinging on liquid. The experimental results show that a small amount of N2 or O2 added in He working gas would significantly change the morphology of jet plume and affect the current amplitude due to the promotion of penning ionization. For bullet propagation, the shape and velocity of the bullet display a huge difference, and it may be strongly dependent on the electric field formed by surface charges deposited on the liquid surface; by comparing touching and not touching the liquid surface, the APPJs impinging on the water illustrate a higher emission intensity of reactive species, particularly OH intensity that is due to the water vapor evaporating into the plasma; for the aqueous RONS (H2O2, NO3−, and NO2−) produced in liquid, it is found that the more the H2O2 production is generated in He + O2 APPJ the higher the NO3− and NO2− concentrations are obtained in He + N2 APPJ. Additionally, the liquid activated by H e + N2 APPJ shows the strongest acidification efficiency due to the more concentrations of HNO3 and HNO2 formation.The understanding of plasma-liquid interactions is of major importance in biomedicine and to better adjust the biological processes induced on/in the biological target by atmospheric pressure plasma jets (APPJs).
