| Research Abstract |
Reactive dynamics between plasma and microorganism was investigated by constructing a novel monitoring system for establishing the science of interaction among gas phase of plasma, surface reaction on microorganism, and life function of microorganism.
Main results are as follows. 1.There is no damage through radical exposure while oxygen species inhibit selective permittivity of membrane and destruct Quinone. 2.Quantitative measurement of ground-state atomic oxygen and excited-state molecular oxygen radicals and evaluation of efficiencies. 3.Cell proliferation and inactivation can be controlled by dose of atomic oxygen.
