Fig. 6From: The Apoptosis Effect on Liver Cancer Cells of Gold Nanoparticles Modified with Lithocholic AcidAnalysis of ROS production after HepG2 cells was treated with AuNP@MPA-PEG-LCA for 6 h. The content of ROS in HepG2 cells was investigated by a confocal microscopy (excitation at 488 nm and emission at 530 nm) and b flow cytometry (excitation at 488 nm and emission at 525 nm)Back to article page
