GO interaction with HeLa cells. (a) Schematic diagram of functionalized GO contacting with cellular surface receptors and invading the cell via endocytosis. Internalized GO flakes are progressively degraded in lysosomes. (b) TEM characterization of GO flakes. (c) Confocal microscopy image of HeLa cells exposed to 50 μg/ml functionalized GO flakes displaying a normal morphology after 72 h exposure.
