Piezocatalytic therapy, which generates reactive oxygen species (ROS) under mechanical force, has garnered extensive attention for its use in cancer therapy owing to deep tissue penetration depth and less O2 -dependence. However, the piezocatalytic therapeutic efficiency is limited poor piezoresponse, low separation of electron-hole pairs, complicated tumor microenvironment (TME). Herein, a biodegradable, porous Mn-doped ZnO (Mn-ZnO) nanocluster with enhanced piezoelectric effect constructed via doping engineering. Mn-doping not only induces lattice distortion increase polarization but also creates rich vacancies (OV ) suppressing recombination leading high-efficiency generation ROS ultrasound irradiation. Moreover, shows TME-responsive multienzyme-mimicking activity glutathione (GSH) depletion ability mixed valence Mn (II/III), further aggravating oxidative stress. Density functional theory calculations show that can improve performance enzyme Mn-ZnO due presence OV . Benefiting from boosting GSH ability, significantly accelerate accumulation lipid peroxide inactivate peroxidase 4 (GPX4) induce ferroptosis. The work may provide new guidance exploring novel sonosensitizers therapy.
