Applying fiber-optics on surface plasmon resonance (SPR) sensors is aimed at practical usability over conventional SPR sensors. Recently, field localization techniques using nanostructures or nanoparticles have been investigated on optical fibers for further sensitivity enhancement and significant target selectivity. In this review article, we explored varied recent research approaches of fiber-optics based localized surface plasmon resonance (LSPR) sensors. The article contains interesting experimental results using fiber-optic LSPR sensors for three different application categories: (1) chemical reactions measurements, (2) physical properties measurements, and (3) biological events monitoring. In addition, novel techniques which can create synergy combined with fiber-optic LSPR sensors were introduced. The review article suggests fiber-optic LSPR sensors have lots of potential for measurements of varied targets with high sensitivity. Moreover, the previous results show that the sensitivity enhancements which can be applied with creative varied plasmonic nanomaterials make it possible to detect minute changes including quick chemical reactions and tiny molecular activities.
将光纤应用于表面等离子体共振（SPR）传感器旨在提高传统 SPR 传感器的实用性。最近，人们研究了使用纳米结构或纳米粒子的光纤场局域技术，以进一步提高灵敏度和显著的目标选择性。在这篇综述文章中，我们探讨了基于光纤的局域表面等离子体共振（LSPR）传感器的各种最新研究方法。本文包含了使用光纤 LSPR 传感器在三个不同应用类别（1）化学反应测量、（2）物理性质测量和（3）生物事件监测中的有趣实验结果。此外，还介绍了可以与光纤 LSPR 传感器相结合产生协同作用的新技术。综述文章表明，光纤 LSPR 传感器具有测量各种目标的高灵敏度的潜力。此外，先前的结果表明，通过创造性地使用各种等离子体纳米材料进行灵敏度增强，可以检测到微小的变化，包括快速化学反应和微小的分子活动。
