Magnetostrictive CoFe₂O₄ (CFO) nanoparticles were encapsulated within a UiO-66 metal–organic-framework layer to form a CFO@UiO-66 nanohybrid. The deforming of CFO, in response to a high-frequency AC magnetic field, initiates the piezocatalytic property of UiO-66 to generate ˙OH radicals, which can kill cancer cells buried in thick tissues, showcasing bright potential for deep-seated tumor treatment.

磁致伸缩-压催化CoFe2O4@UiO-66纳米杂化材料及其治疗深部肿瘤的潜力

磁致伸缩CoFe ₂ O ₄ (CFO)纳米颗粒被封装在UiO-66金属有机骨架层内，形成CFO@UiO-66纳米杂化物。 CFO在高频交流磁场的作用下发生变形，启动UiO-66的压电催化特性，产生˙OH自由基，可以杀死埋藏在厚组织中的癌细胞，展示了深部肿瘤治疗的光明潜力。
