Abstract The tumor microenvironment (TME) is characterized by hypoxia and low immunogenicity, with a dense rigid extracellular matrix (ECM) that impedes the diffusion of therapeutic agents immune cells, thereby limiting efficacy immunotherapy. To overcome these challenges, an oxygen defect piezoelectric‐photothermal sensitizer, bismuth vanadate nanorod‐supported platinum nanodots (BVP) developed. integration enhances photothermal effect improves charge separation efficiency under ultrasound, leading to increased heat generation production reactive species (ROS) oxygen. Platinum also catalyzes conversion hydrogen peroxide in TME oxygen, which serves as both ROS source means alleviate hypoxia, reversing immunosuppressive TME. Moreover, coordination ions glutathione further amplifies cellular oxidative stress. generated not only denature collagen ECM, facilitating deeper penetration BVP into but induce immunogenic cell death cells. Through “degeneration penetration” strategy, photoacoustic therapy effectively activates inhibiting growth metastasis. This study introduces pioneering approach design antitumor nanomedicines aimed at characteristics
