Abstract The inherent and unique charge‐carrier release characteristics of piezoelectric sonosensitizers with desired bandgap can be leveraged to initiate reactive oxygen species (ROS) reactions that have considerable potential for sonodynamic therapy (SDT). In this study, a bimetallic Bi 4 NbO 8 Br‐polyvinylpyrrolidone (BNOBP) small (2.45 eV) is synthesized as sonosensitizer. robust interactions within between the Bi─O Nb─O layers narrow bandgap, facilitating carrier transfer. Concurrently, compared TiO 2 BiOBr, BNOBP exhibits rapid acoustoelectric response desirable electron–hole separation efficiency, enabling generation ·O − under ultrasound (US) irradiation. Notably, alleviates overexpression glutathione (GSH) in tumors prevents consumption generated ROS by GSH. Combining previous endow high study provides paradigm situ regulation oxidative stress levels tumor tissue microenvironment based on sonosensitizers.
