表面等离子体共振(SPR)在化学传感器和生物传感器中有着广泛的应用。等离子体激元在不同类型的光学传感器中起着不同的作用。SPR通过响应于外部刺激的光谱位置和强度的变化来转换比色传感器中的信号。SPR还可以将入射电磁场集中在纳米结构中,调制荧光发射并使等离子体增强的荧光能够用于超灵敏检测。此外,等离子体激元已广泛用于在表面增强拉曼散射传感器中放大拉曼信号。本文综述了等离子体增强光学传感的最新研究进展,重点介绍了等离子体增强传感器的物理基础以及这些原理如何指导传感器的设计。特别是,本文讨论了纳米材料和纳米结构的等离子体增强光学传感信号的设计策略,还强调了等离子体增强光学传感器在医疗保健,国土安全,食品安全和环境监测中的应用。
Surface plasmon resonance (SPR) has found extensive applications in chemi-sensors and biosensors. Plasmons play different roles in different types of optical sensors. SPR transduces a signal in a colorimetric sensor through shifts in the spectral position and intensity in response to external stimuli. SPR can also concentrate the incident electromagnetic field in a nanostructure, modulating fluorescence emission and enabling plasmon-enhanced fluorescence to be used for ultrasensitive detection. Furthermore, plasmons have been extensively used for amplifying a Raman signal in a surface-enhanced Raman scattering sensor. This paper presents a review of recent research progress in plasmon-enhanced optical sensing, giving an emphasis on the physical basis of plasmon-enhanced sensors and how these principles guide the design of sensors. In particular, this paper discusses the design strategies for nanomaterials and nanostructures to plasmonically enhance optical sensing signals, also highlighting the applications of plasmon-enhanced optical sensors in health care, homeland security, food safety and environmental monitoring.
