| Outline of Final Research Achievements |
In this study, we have quantitatively clarified the doses of radicals for activating, suppressing, inactivating spores, bacteria, or cells in the atmosphere or solutions. Besides, we have almost elucidated the mechanisms of activation and inactivation of cells and so on from the quantitative results of intracellular structural changes and of the concentrations of hydrogen peroxide, hypochlorous acid, and nitrate ions generated in the solutions irradiated with radicals using various spectroscopies. Furthermore, as for cultured animal cells, we have almost clarified the signal path of selective inactivation using melanoma and mouse fibroblast cells.
