(a) Optical emission spectrum measured by CCD spectrometer with optical fiber at the 2 mm above and below region, respectively, of the DI water under Ar plasma jet bombardment onto the biosolution surface with inclusion of Ar gas in glove box; (b) Lifetimes for various ROS measured at ambient air region of 2 mm above the water surface without Ar glove box by using the monochromator; (c) Temporal behaviors of 309 nm for OH• emission intensity for different depth locations of 2 mm, 4 mm and 6 mm inside the DI solution with quartz filter located at 1 mm depth position of water during Ar plasma jet bombardment; (d) Lifetimes of OH• vs water depth positions for 2 mm, 4 mm and 6 mm from the surface.
