FAP and neoplasm: For example, the diagnostic time of 89Zr‐Df‐tinurilimab PET imaging was prolonged, and the β–ray treatment of 131I‐tinurilimab treatment was less effective and safety than that of α–ray particle treatment (212Pb and 225Ac).[47, 48] To address this deficiency, the structural optimization of antibodies (such as nano–antibodies) and the optimization of diagnostic nuclides (such as 68Ga labeling) can be implemented, such as 68Ga/255AC–DOTA–4AH29 for theranostic of FAP‐positive tumor.[49] These modifications are also ongoing in the subsequent experiments.
