Recently, biomedical research on non-equilibrium atmospheric pressure plasma has received much attention, and electrically neutral active species are considered to be effective species for various plasma biological phenomena. However, the density of the active species supplied from the plasma and the newly generated active species as a result of the reaction in the liquid differs depending on their lifetimes, and the effect exerted by the position of the sample in the liquid also differs. In this study, we investigated the transportation of reactive oxygen species in liquid using potassium iodide starch liquid reagent in order to obtain efficient results of active species acting on samples.
