(A) A schematic illustration of Au-IONP-Affibody. (B) A TEM image of Au-IONP. (C) A high-angle annular dark field image of Au-IONP. The Au nanoparticles were shown as the bright dots. (D) In vivo PET imaging of A431 tumor-bearing mice acquired 24 h after the injection of 64Cu-NOTA-Au-IONP-Affibody. From left to right: targeted group and blocking group. (E) In vivo MR imaging of A431 tumor-bearing mice acquired 24 h after the injection of 64Cu-NOTA-Au-IONP-Affibody. Tumors were marked by yellow arrow-heads. Reprinted with permission from [43].
