Plasma treatment mechanism of chemical or biological sample in a solution is still an open question. Reactive radical transport is an important factor, but its convenient monitoring has been lacking. In this presentation, preliminary results for using iodine-starch reaction as a monitoring tool will be shown. Effect of media viscosity or working gas on radical transport is also studied.
