Endocytosis inhibition experiments. (A, B) Representative fluorescence images of HeLa cells incubated with AuNP-SVS-1 (2 nM) and AuNR-SVS-1 (0.2 nM) conjugates for 40 min at 4 °C (top panels), in the presence of sodium azide (middle panels) and in the presence hypertonic sucrose solution (bottom panels). The cell nuclei were DAPI stained. Scale bar ∼ 10 μm.
