Figure 4
Au 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 AuNPs. The measured intensity and area of each ROS fluorescence are displayed, and in both cases the OH-radical fluorescence showed a gradual decrease with depth. |
