| Research Abstract |
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.
