The harsh environment of diabetic wounds, including bacterial infection and wound hypoxia, is not conducive to wound healing. Herein, an enzyme-like photocatalytic octahedral Rh/AgMoO is developed to manage diabetic-infected wounds. The introduction of Rh nanoparticles with catalase-like catalytic activity can enhance the photothermal conversion and photocatalytic performance of Rh/AgMoO by improving near-infrared absorbance and promoting the separation of electron-hole pairs, respectively. Rh/AgMoO can effectively eliminate pathogens through a combination of photothermal and photocatalytic antibacterial therapy. After bacteria inactivation, Rh/AgMoO can catalyze hydrogen peroxide to produce oxygen to alleviate the hypoxic environment of diabetic wounds. The in vivo treatment effect demonstrated the excellent therapeutic performance of Rh/AgMoO on diabetic infected wounds by removing infectious pathogens and relieving oxygen deficiency, confirming the potential application of Rh/AgMoO in the treatment of diabetic infected wounds.
糖尿病伤口恶劣的环境,包括细菌感染和伤口缺氧,不利于伤口愈合。在此,开发了一种酶样光催化八面体 Rh/AgMoO 来管理糖尿病感染的伤口。引入具有类过氧化氢酶催化活性的 Rh 纳米粒子可以分别通过提高近红外吸收和促进电子-空穴对的分离来增强 Rh/AgMoO 的光热转换和光催化性能。Rh/AgMoO 可以通过光热和光催化抗菌疗法的结合有效地消除病原体。在细菌失活后,Rh/AgMoO 可以催化过氧化氢产生氧气,以缓解糖尿病伤口的缺氧环境。体内治疗效果证明了 Rh/AgMoO 通过消除感染病原体和缓解缺氧对糖尿病感染伤口的优异治疗效果,证实了 Rh/AgMoO 在治疗糖尿病感染伤口方面的潜在应用。
