Fig. 3From: The Apoptosis Effect on Liver Cancer Cells of Gold Nanoparticles Modified with Lithocholic AcidMorphologic characteristics of cell nucleus of HepG2 cells stained with Hoechst 33342. HepG2 cells were incubated with AuNP@MPA-PEG-LCA (0.5 mg/ml) for a 0 h, b 24 h, and c 48 h, and d AuNP@MPA (0.5 mg/ml) incubated for 48 h. Apoptotic cells displayed condensed and fragmented nuclei, and shrinkage of cell volume; scale bar 20 μmBack to article page
