缺陷工程多铁催化平台实现微波与声动力级联响应治疗骨髓炎
Harnessing Defect Engineered Multiferroic Catalysts for Cascade Responsive Microwave and Sonodynamic Therapy in Osteomyelitis
AI 导读
将锰掺杂铁酸铋纳米催化剂与地黄-黄精来源细胞外囊泡整合于可注射水凝胶，构建出缺陷工程多场响应催化平台。DFT计算表明Mn掺杂引入缺陷偶极、抑制漏电流并增强介电损耗与压电响应，微波辐照产生局部升温降低催化势垒，后续超声促进压电电荷分离高效生成活性氧，协同清除慢性骨髓炎深部生物膜；水凝胶降解释放的细胞外囊泡调控巨噬细胞极化并促进骨再生。
