a Cell viabilities of C6 cells after treatment with various concentrations of glucose with or without GOD@POMs or POMs. b Cell viabilities of C6 cells after treatment with GOD@POMs at various concentrations with or without laser irradiation (1064 nm, 1 W/cm2, 5 min). c Cell viabilities of C6 cells after different treatments: (I) Control; (II) Laser; (III) GOD@POMs; (IV) GOD@POMs + Laser; (V) GOD@POMs + Glucose; (VI) GOD@POMs + Glucose + Laser. d CLSM images of C6 cells stained with Calcein AM and PI after varied treatments. e Flow cytometry apoptosis assay of C6 cells stained by Annexin-FITC and PI after varied treatments. f CLSM images and flow cytometry of intracellular ROS production of C6 cells stained with DCFH-DA after different treatments. Scale bar: 100 μm. ***p < 0.001, **p < 0.01 and *p < 0.05
