| Outline of Final Research Achievements |
In the cases of plasma-biomedical applications, targets usually include a large amount of liquid. The chemical interaction between plasma and liquids have to be understood for safe and effective use of plasma technology. However, the mechanisms for chemical reactions in the liquid targets induced by plasma irradiation is currently unavailable in detail. Therefore, we have studied the chemical reactions in a tissue model using our original method. The method can visualize two-dimensional distribution of oxidation reactions even in a tissue model. As a result, we clarified the relationship between plasma irradiation conditions and the oxidation reactions in a tissue model. We indicated that the distributions of the oxidation reactions can be controlled by plasma irradiation conditions.
