Outline of Final Research Achievements

Various gas atmospheric nonthermal plasmas were generated using a multigas plasma jet to treat E.coli suspensions. Oxygen plasma had high sterilization effects, killed >6 log of E. coli. The liquid phase induced by oxygen plasma jet also had microbial inactivation against S. aureus, P. aeruginosa, C. albicans, and A. niger.
We developed the plasma probe for the endoscopy treatment by 3D printer. The diameter of the probe was 3.7mm. We checked the effect of plasma exposure on the porcine bile duct and liver using the probe. The plasma exposure did not induce tissue damage.
