Tumor-targeting profiles of HA-VE/PBAEss NPs in vivo by IVIS spectrum. a Schematic diagram showing the preparation of the fluorescent NPs using DiR dye loaded in HA-VE/PBAEss NPs using a similar approach as that used with TPL/NPs. b Fluorescent distribution of DiR/NPs in vivo after vein injection at predetermined time intervals, i.e., 0, 0.5, 2, 4, 6, 12, 24, 36, 48, and 72 h after injection. c Ex vivo fluorescence images of dissected organs of the mice 72 h postinjection
