Plasmonic sensing has been an important multidisciplinary research field and has been extensively used in detection of trace molecules in chemistry and biology. The sensing techniques are typically based on surface-enhanced spectroscopies and surface plasmon resonances (SPRs). This review article deals with some recent advances in surface-enhanced Raman scattering (SERS) sensors and SPR sensors using either localized surface plasmon resonances (LSPRs) or propagating surface plasmon polaritons (SPPs). The advances discussed herein present some improvements in SERS and SPR sensing, as well as a new type of nanowire-based SPP sensor.
等离子体传感一直是一个重要的多学科研究领域，并已广泛应用于化学和生物学中痕量分子的检测。传感技术通常基于表面增强光谱和表面等离子体共振（SPR）。这篇综述文章论述了使用局域表面等离子体共振（LSPR）或传播表面等离子体激元（SPP）的表面增强拉曼散射（SERS）传感器和SPR传感器的一些最新进展。本文讨论的进展展示了SERS和SPR传感方面的一些改进，以及一种新型的基于纳米线的SPP传感器。
