(A) A schematic illustration of the 64Cu-NOTA-IONP(DOX)-cRGD nanoconjugates for combined tumor-targeted drug delivery and PET/MRI imaging. (B) A TEM image of IONP(DOX)-cRGD. (C) In vivo PET images of U87MG tumor-bearing mice 24 h after injection of different nanoconjugates. From left to right: targeted group (64Cu-NOTA-IONP-cRGD), non-targeted group (64Cu-NOTA-IONP) and blocking group. Tumors were marked by yellow arrow-heads. Reprinted with permission from [41].
