Enhanced Spin‑Engineering Photothermoelectric–Enzymatic Catalysis System via Lattice Mismatch‑Induced Jahn–Teller Distortion for Tumor Therapy (IMAGE)
Caption
- A Fe3O4–Ag2S p–n heterojunction is engineered to induce interfacial Jahn–Teller distortion, which modifies d-orbital splitting and enhances spin-polarized catalytic activity for synergistic tumor therapy.
- The photothermal-driven thermoelectric effect generates an electric field that facilitates directional charge separation, concurrently boosting multiple enzyme-mimicking activities for enhanced catalytic therapy.
- Density functional theory calculations confirm that the Jahn–Teller distortion optimizes the d-orbital and spin state of Fe3+, providing a theoretical basis for the superior thermoelectric and enzymatic performance.
