Fluorescent intracellular distribution, and cytotoxicity of GS-CDs in SH-SY5Y cells with time. a Fluorescence microscope images of the SH-SY5Y cells and GS-CDs (100 µg·mL− 1) incubated at different times (30 min, and 2, 4, 6, 12, 24, and 48 h). The scale bars were 50 μm. b In vitro cytotoxicity profiles of the SH-SY5Y cells after incubating with the GS-CDs at different times (6, 12, 24, and 48 h). Data were mean ± s.d. (n = 6). *p < 0.05, **p < 0.01 and ***p < 0.001 relative to 0 µg·mL− 1, as analyzed by one-way ANOVA.
