摘要/Abstract

摘要： 慢性鼻窦炎(CRS)常因金黄色葡萄球菌病原体的检出而复杂化，对传统治疗方式构成重大临床挑战。同时，电磁干扰和辐射问题不仅对可穿戴医疗设备功能造成潜在威胁，也对人体健康构成风险。本文开发了一种多功能三聚氰胺泡沫复合材料，通过将二维碳化钛(Ti₃C₂T_x) MXene和银纳米线(AgNWs)整合到三聚氰胺泡沫骨架上，再包覆聚二甲基硅氧烷层以增强生物相容性和自清洁性能，从而实现高效杀菌。所得三聚氰胺泡沫/MXene/AgNWs/聚二甲基硅氧烷(MMAP)复合材料在近红外照射下表现出优异的光热转换能力。结合银离子的持续释放，对金黄色葡萄球菌实现了99.86%的杀菌率。同时，互连的MXene/AgNWs网络赋予该材料优异的导电性和30.1 dB的电磁屏蔽效能。本研究为设计兼具电磁屏蔽、光热杀菌活性和自清洁性能的集成生物材料提供了潜在方法，在抗细菌感染及抑制电磁辐射领域具有应用前景。

Abstract: Chronic rhinosinusitis (CRS), often complicated by detection of Staphylococcus aureus (S. aureus) pathogens, poses a significant clinical challenge to conventional treatment methods. Meanwhile, the electromagnetic interference (EMI) and radiation concerns have caused potential threats to not only wearable medical device functionality but also to human health. Herein, a multifunctional melamine foam (MF) composite is developed for efficient bacterial eradication, which is fabricated through integrating Ti₃C₂T_x MXene and Ag nanowires (AgNWs) onto melamine foam skeleton, followed by encapsulation with a polydimethylsiloxane (PDMS) layer to increase the biocompatibility and self-cleaning property. The resulting melamine foam/MXene/AgNWs/PDMS (MMAP) composite exhibits outstanding photothermal conversion under near-infrared (NIR) irradiation. When combined with the sustained release of Ag⁺ ions, excellent antibacterial action against S. aureus with 99.86% sterilization rate was achieved. Simultaneously, the interconnected MXene/AgNWs network confers excellent electrical conductivity and and EMI shielding effectiveness of 30.1 dB. This study offers a potential method for designing integrated bio-materials that combine electromagnetic shielding, photothermal bactericidal activity and self-cleaning property, offering potential applications in preventing bacterial related infections, as well as suppressing EM radiation.

Key words: MXene, EMI shielding, Chronic rhinosinusitis, Staphylococcus aureus
