—On-site analysis of multiple analytes from different classes (such as heavy metals, proteins and small molecules), at the sensitivity required for a selected application, is a hard technological challenge. In this context, optical sensing in miniaturized systems has the largest potential. We present here the design and optimization of a miniaturized optical sensor with multiple channels, capable of multimodal optical detection in each channel, and the proof-of-concept realization of sub-systems providing two complementary detection modes: plasmon enhanced fluorescence and localized surface plasmon resonance. The multichannel (enabling multiplexing) and multimodal optical sensor is designed to have a total size of one inch-square and optimized sensing performance, obtained by combining organic optoelectronic and nanoplasmonic components.

基于有机光电子学和纳米等离子体学的多重和多模态检测光学传感器的设计

— 以选定应用所需的灵敏度对不同类别的多种分析物（例如重金属、蛋白质和小分子）进行现场分析是一项艰巨的技术挑战。在这种背景下，微型系统中的光学传感具有最大的潜力。我们在这里展示了具有多个通道的小型化光学传感器的设计和优化，能够在每个通道中进行多模态光学检测，以及提供两种互补检测模式的子系统的概念验证实现：等离子体增强荧光和局域表面等离子体谐振。该多通道（支持多路复用）和多模态光学传感器的设计总尺寸为一平方英寸，并通过有机光电和纳米等离子体组件的结合获得了优化的传感性能。
