Human umbilical vein endothelial cells (HUVECs) treated with europium(III) hydroxide nanorods (center figure) indicate the internalization of these nanorods to the cytoplasm of the cells. Chick chorioallantoic membrane (CAM) assay of HUVECS treated with the nanorods shows the formation of vascular sprouting, which supports in vivo angiogenesis.
