(A) Viability of U87MG cells after 24 h of incubation with Mn-ZGGOs. (B) Confocal images of U87MG cells stained by SOSG after incubating with PBS or Mn-ZGGOs for 24 h. The green fluorescence indicates the presence of 1O2. (C) Confocal images of U87MG cells stained by DCFH-DA after incubating with PBS or Mn-ZGGOs for 24 h. The green fluorescence indicates the presence of ·OH. (D) Confocal images of lipoperoxides in U87MG cells after incubation with PBS or Mn-ZGGOs for 24 h. The green fluorescence is the lipid ROS after the staining with BODIPY C11. (E) Confocal images of the changes in the mitochondrial membrane potential of U87MG cells after incubation with PBS or Mn-ZGGOs for 24 h. The red fluorescence indicates that the membrane potential is positive, and the green fluorescence indicates that the membrane potential decreases. (F) Confocal images of U87MG cells with production of O2 stained by [Ru(dpp)3]Cl2 after incubating with Mn-ZGGOs versus times. The blue fluorescence from Hochest 33342 indicatesthe cell nuclei in (b-e). Scale bar: 40 μm.
