Cited from a previous study (Detappe et al. 2015). a TEM image (3000×) depict the active endocytosis uptake of AGuIX into the Panc1 tumor cells. Bar 5 μm. b Magnified TEM image (25,000×) shows AGuIX nanoparticles captured by endosomal vesicles (black arrow) and carried into the cytoplasm. Bar 1 μmBack to article page
