Development of a novel disinfection technique based on photodynamic therapy

在本研究中，它被证明在光动力疗法中产生的单线态氧可以有效地杀死金黄色链球菌。此外，还建立了光动力疗法中产生的单线态氧的定量分析方法。结果表明，采用空间位阻胺的电子自旋共振技术是一种可行的方法。分析表明，单线态氧的产率随辐照时间和光敏剂浓度的增加而增加。

In the present study, it was demonstrated that singlet oxygen generated in photodynamic therapy could effectively kill Streptococcus aureus. In addition, a quantitative analytical method for singlet oxygen generated in photodynamic therapy has been established. It was demonstrated that electron spin resonance technique using sterically hindered amine was suitable for the measurement. The analysis showed that the yield of singlet oxygen increased with the irradiation time and the concentration of photosensitizer.
