报道了空气和氮气等离子体射流对四种不同生理溶液和去离子水中大肠杆菌的影响。进料气体被发现影响等离子体组合物，与液体的相互作用，以及随后的杀菌效果取决于它们所暴露的水溶液。空气等离子体通过酸化增强去离子水和盐水的杀菌效果。另一方面，N2等离子体通过产生更多电子而在磷酸盐缓冲盐水中诱导更高的毒性。细胞培养基和血浆的杀菌作用很小，可能是由于pH值的轻微变化和有机组分的电子清除。总之，我们的研究为生理溶液中血浆和细胞之间的基本相互作用提供了额外的见解。[图形]。
The effects of air and N2 plasma jets on Escherichia coli inside four different physiological solutions and deionized water are reported here. The feeding gases are found to influence the plasma compositions, the interactions with the liquids, and the subsequent bactericidal effects depending on the aqueous solutions to which they are exposed. Air plasma enhances the bactericidal effects of deionized water and saline by acidification. On the other hand, N2 plasma induces higher toxicity in phosphate buffered saline by generating more electrons. Little bactericidal effects of cell culture media and blood plasma may be due to the slight change in the pH and due to electron scavenging by organic components. Taken together, our study provides additional insight into the basic interactions between plasma and cells in physiological solutions.[GRAPHICS].
