Figure 5
Fe X-FL-derived planar ROS distribution detected by APF gel [green fluorescence (a) and (b)] or DHE gel [red fluorescence (c) and (d)] under X-ray irradiation in the absence (b and d) or presence (a and c) of FeONPs. The measured intensity and area of each ROS fluorescence are displayed, and the OH radicals show a gradual decrease in intensity and increase in area with depth. |
