Fig. 5.

Confocal images of HeLa cells after incubation with AIE-PS dots and Au585@AIE-PS for 12 h (First column, red fluorescence). The nuclei were stained with Hoechst 33,342 (5 μg mL⁻¹, 5 min) with blue emission. The difference in the contrast of bright field images (last column) indicates the internalization of Au nanostars in the cells. All the images share the same scale bar of 50 μm
