Radioiodinated Persistent Luminescence Nanoplatform for Radiation‐Induced Photodynamic Therapy and Radiotherapy

Radionuclide with Cerenkov radiation (CR) can serve as an internal excitation source to activate photosensitizers for photodynamic therapy (PDT) in deep tumor. However, the low efficiency of CR limits its therapeutic efficacy. A 131 I labeled zinc tetra(4‐carboxyphenoxy) phthalocyaninate (ZnPcC4) conjugated Cr 3+ ‐doped zinc gallate (ZnGa 2 O 4 :Cr 3+ , ZGCs) nanoplatform ( 131 I‐ZGCs‐ZnPcC4) is developed for radiotherapy (RT) and...
