Nanozyme‐Based Biomimetic Intelligent Immune Organelles for the Treatment of Bladder‐Metastasized Tumors

demonstrates enhanced tumor accumulation and promotes synergistic catalytic‒photothermal therapy, inducing immunogenic cell death and promoting immune activation through the release of adjuvants. Consequently, the efficacy of PD-L1 nb is significantly improved, leading to the effective eradication of tumor cells and the inhibition of recurrence and metastasis.
