Single-atom nanozymes (SAzymes), with individually isolated metal atom as active sites, have shown tremendous potential enzyme-based drugs for enzymatic therapy. However, using SAzymes in tumor theranostics remains challenging because of deficient activity and insufficient endogenous H2O2. We develop an external-field-enhanced catalysis by atom-level engineered FeN4-centered nanozyme (FeN4-SAzyme) radio-enzymatic This FeN4-SAzyme exhibits peroxidase-like capable catalyzing H2O2 into hydroxyl radicals converting single-site FeII species to FeIII subsequent glutathione oxidase-like activity. Density functional theory calculations are used rationalize the origin self-cascade Importantly, X-rays can improve overall cascade reaction process via promoting conversion frequency FeII/FeIII. As a producer, natural glucose oxidase is further decorated onto surface yield final construct GOD@FeN4-SAzyme. The resulting GOD@FeN4-SAzyme not only supplies situ continuously produce highly toxic but also induces localized deposition radiation dose, subsequently inducing intensive apoptosis ferroptosis vitro. Such synergistic effect radiotherapy therapy allows improved growth inhibition minimal side effects vivo. Collectively, this work demonstrates introduction external fields enhance enzyme-like performance without changing their properties highlights robust therapeutic self-supplying amplifying reactions address limitations treatment.

G-IrTe2 sonosensitizer under ultrasound (US) stimuli exhibits excellent reactive oxygen species (ROS) production performance. Besides, catalase (CAT)-like activity can provide abundant to enhance SDT effect. Then, theoretical calculation verifies that US easily make irregular be broken in amorphous free electrons will released combine further form singlet (1O2). Meanwhile, peroxidase (POD)-like also catalyze endogenous H2O2 produce more ROS which conducive better tumor ablation. Furthermore, produced by sono-/chemodynamic processes cause mitochondrial dysfunction give rise heat shock protein (HSP) downregulated expression, maximizing efficiency PTT. Therefore, such rich defect could involved oncotherapy then effectively outstanding efficacy. This study provides new research idea expanding application inorganic nanomaterials promoting therapeutic effect tumors.
