WebApr 13, 2024 · When oxidized by ROS, DCFH-DA is converted to green-fluorescing 2′-7′-dichlorofluorescein (DCF). As shown in Figure 3 b, e, very little green fluorescence was observed in the control, whereas the UMRC-6 cells incubated with Fe-OH, Ni-OH, and Fe/Ni-LDH showed green fluorescence. WebApr 13, 2024 · DCFH-DA could penetrate cells and be oxidized by intracellular ROS to generate fluorescent DCF, thus it was used as a detective probe for intracellular ROS levels. The L929 cells were treated with H 2 O 2 to generate ROS, and then incubated with the extractions of hydrogels.
