A new generation of an FFP2 (Filtering Face Piece of type 2) smart face mask is achieved by integrating broadband hybrid nanomaterials and a self-assembled optical metasurface. The multifunctional FFP2 face mask shows simultaneously white light-assisted on-demand disinfection properties and versatile biosensing capabilities. These properties are achieved by a powerful combination of white light thermoplasmonic responsive hybrid nanomaterials, which provide excellent photo-thermal disinfection properties, and optical metasurface-based colorimetric biosensors, with a very low limit of pathogens detection. The realized system is studied in optical, morphological, spectroscopic, and cell viability assay experiments and environmental monitoring of harmful pathogens, thus highlighting the extraordinary properties in reusability and pathogens detection of the innovative face mask.
新一代 FFP2（过滤式面罩 2 型）智能面罩通过集成宽带混合纳米材料和自组装光学超表面实现。多功能 FFP2 面罩同时显示按需白光辅助消毒性能和多功能生物传感能力。这些特性是通过强大的组合实现的，包括白光热等离子体响应混合纳米材料，提供出色的光热消毒性能，以及基于光学超表面的比色生物传感器，具有非常低的病原体检测极限。所实现的系统在光学、形态学、光谱学和细胞活力测定实验以及有害病原体的环境监测中进行了研究，从而突出了创新面罩在可重复使用和病原体检测方面的卓越性能。
