Transferrin‐Targeted Nanoarchitectonics with Efficient Metastasis Inhibition Enabling Tumor T1‐T2 Dual‐Mode Magnetic Resonance Contrast Enhancement

S inhibited catalase activity, providing additional substrates for the Fenton-like reaction, thereby amplifying CDT in a cascading manner. This synergistic mechanism amplified the cytotoxicity of CDT, enhancing the efficacy of tumor treatment and metastasis inhibition. Therefore, FMT demonstrated significant promise for enhancing both the precision of tumor imaging and the efficacy of treatment.
