Smart contact lenses with electronic circuits are rapidly advancing for health monitoring and sensing applications, but concerns over electromagnetic (EM) radiation exposure remain. As these devices are near commercialization, protecting the eyes from such radiation is crucial. MXenes (M X T , where M is a transition metal, X is carbon and/or nitrogen, and T denotes the functional groups [e.g., -OH, -F, =O, etc.]), a class of 2D transition metal carbides/nitrides, offer exceptional properties such as high conductivity, biocompatibility, and strong EM shielding, making them ideal for preventing radiation-induced eye diseases like cataracts. Herein, an MXene-coated contact lens platform that effectively reduces EM radiation exposure while maintaining over 80% visible light transmission, 90% cell viability, and robust shielding capabilities is presented. This approach achieves stable integration of MXene nanosheets on soft contact lenses and mitigates their oxidation degradation. The lens also enhances dehydration protection and demonstrates safety by showing no signs of inflammation or adverse effects in rabbit eyes. These findings highlight MXene-coated contact lenses as a promising solution for next-generation wearable technologies and healthcare applications.
带有电子电路的智能隐形眼镜在健康监测和传感应用方面正迅速发展，但对电磁辐射暴露的担忧依然存在。随着这些设备接近商业化，保护眼睛免受此类辐射至关重要。MXenes（MₓTₙ，其中M是过渡金属，X是碳和/或氮，Tₙ表示官能团[例如，-OH、-F、=O等]），一类二维过渡金属碳化物/氮化物，具有高导电性、生物相容性和强电磁屏蔽等优异性能，使其成为预防白内障等辐射诱发眼病的理想材料。在此，我们展示了一种涂覆有MXene的隐形眼镜平台，该平台在保持超过80%的可见光透过率、90%的细胞活力和强大屏蔽能力的同时，能有效减少电磁辐射暴露。这种方法实现了MXene纳米片在软性隐形眼镜上的稳定整合，并减轻了它们的氧化降解。该隐形眼镜还增强了脱水保护能力，且在兔眼中未显示出炎症或不良反应迹象，证明了其安全性。这些发现凸显了涂覆有MXene的隐形眼镜作为下一代可穿戴技术和医疗保健应用的一种有前景的解决方案。
