The distribution of ZIF-90-RhB in larval zebrafish and light-lesioned retina. a Bright field and fluorescence images of larval zebrafish following ZIF-90-RhB exposure at 96 and 120 hpf. b Time-lapse localization of ZIF-90-RhB in sections taken from light-lesioned retinas from 1 to 7 days post-lesion (dpl). The lesion sites are indicated by the dotted rectangles. c Quantitative analysis of the fluorescence area (ANOVA; **P < 0.01). Scale bars in a: 500 μm; b: 20 μm. RPE retinal pigment epithelium; OSL outer segment layer; ONL outer nuclear layer; ON optic nerve
