Fig. 6From: Mechanistic study of silica nanoparticles on the size-dependent retinal toxicity in vitro and in vivoSiO2 NPs induce mitochondrial dysfunction. R28 cells were treated with three concentrations (20, 40, and 80 μg/mL) of SiO2 NPs for 6 h (A), 12 h (B) and 24 h (C), and mitochondrial membrane potential was evaluated by JC-1 staining.
