Cellular internalization of gold nanoparticles in HUVECs: (A) cells treated with GCg-AuNPs (50 µg/mL), 2 h; (B) cells pretreated with laminin receptor blocking antibody (ABLR), then treated with EGCg-AuNPs (50 µg/mL), 2 h; (C) cells treated with starch functionalized gold nanoparticles (50 µg/mL), 2 h; images were captured by transmission electron microscopy. HUVECs (human umbilical vein endothelial cells).
