Outline of Final Research Achievements

We proposed a new medical technology utilizing reactive species produced by photochemical process using vacuum ultraviolet light (VUV). It would be used for, for example, cancer treatment and wound healing. The VUV light produces such as O and OH from O2 and H2O. We made the equipment and confirmed that the system produces reactive species with densities expected by simulation. We treated bacteria with OH radicals produced by this system and showed that this system can produce sufficient amount of OH radicals to cause sterilization, which is important for wound healing. It was shown that this method can also be used for quantitative analysis of medical effect of each reactive species in plasma medicine which is intensively studied these days. This method contributes to the development of plasma medicine.
