Outline of Final Research Achievements

Using developed temperature-controllable multi-gas plasma, generation of reactive species, bacterial inactivation, optimization of plasma source and effect on living body were investigated for medical application. As the results, it is found that nitrogen plasma and carbon dioxide plasma, which generate a large amount of OH radical and singlet oxygen, have high bacterial inactivation effect. We suggest plasma bubble water, and the bacterial inactivation effect was confirmed. Using 3D printer, we succeeded to develop new plasma source, which can be inserted in endoscope. And the treatments with these plasma sources were free from damage to living body.
