TEM images of NR8383 nuclear morphology after exposure to AG-QDs (0, 50, 100, and 200 μg/mL) for 24 h. The images in Panel (b) are enlarged from panel (a). In panel (b), the yellow box indicates the shrinking of the inner nuclear envelope after AG-QDs (50 μg/mL) exposure. The red boxes indicate the malformation of nuclear morphology after AG-QDs (100 and 200 μg/mL) exposure. The blue arrows indicate the chromatin condensation (electron-dense, black structure along nuclear membrane) within the nuclei
