摘要: 光纤表面等离子体共振(surface plasmon resonance,SPR)传感器是未来SPR传感技术发展和系统微型化的自然延伸,但光纤型SPR传感器无法有效解决灵敏度低以及实现多通道测量困难两大瓶颈问题.近年来,该课题组借鉴微结构光纤构建微缩集成SPR传感器的思路,对微结构光纤SPR传感器技术进行了初步探索,其目的是既提高SPR传感器探测灵敏度,同时又解决生物化学传感的多通道测量这两个关键问题.利用微结构光纤实现SPR传感器,可极大地缩小SPR系统的体积,更易于光学器件在光纤中的集成,因而具有广阔的应用前景.

Abstract: Fiber-based surface plasmon resonance (SPR) sensor is the extension and development of the traditional prism-based SPR sensor. Two bottlenecks limit the application of fiber-based SPR sensors:the testing sensitivity is relative low and it is difficult to perform the multichannel sensing detection. In recent years, we explore a SPR sensing technology based on the micro-structured fiber, and construct various micro-structured fiber-based SPR sensors, which break through the current two problems:improving the detecting sensitivity and performing the multi-channel measurement of biochemical sensing. The utilization of microstructure fibers for SPR sensors contributes to reducing the size of the sensing system greatly, ensuring the convenience of integrating with the optical fiber system. In summary, the microstructure fiber-based SPR sensors have a broad application prospects.

Key words: microstructure fiber, sensitization of SPR, SPR multi-channel detection, fiber sensing, surface plasmon resonance (SPR)
