通过对大肠杆菌存活细胞和胞质钾渗漏的分析以及形态学观察，探讨了大气压氩等离子体流动后放电紫外辐射杀灭大肠杆菌的机理。E.大肠杆菌的感染是由于细胞质膜和外膜在等离子体暴露下的破坏以及核酸通过暴露于来自等离子体源的紫外线辐射而被破坏。(c)2006年，美国物理学会。
A mechanism for sterilizing Escherichia coli by a flowing postdischarge and UV radiation of argon plasma at atmospheric pressure was investigated by analyzing the surviving cells and the potassium leakage of cytoplasmic material and by morphological observation. Inactivation of E. coli results from the destruction of the cytoplasmic membrane and the outer membrane under plasma exposure and the destruction of nucleic acids by exposure to ultraviolet radiation from the plasma source.
