A Cell viability of different Gel@ZIF-8 on L929 cells at 24 h and 48 h. B The photo of live/dead cell staining at 48 h. (scale bar = 100 μm). C Fluorescence intensity of the live/dead cell staining at 48 h. D Cell viability of L929 cells with various H2O2 concentrations. E Cytoprotective effect of Gel@ZIF-8 under a highly oxidative medium (H2O2) (n = 3). *, ** and *** indicate p < 0.05, p < 0.01 and p < 0.001, respectively
