在第 1 章中。 J. Homola 在本卷的第 1 篇文章中 [1] 介绍了表面等离子体激元作为电介质/金属平面波导的模式，并确定了它们的特性。已经证明，表面等离子体激元的传播常数对支撑表面等离子体激元的金属膜表面处的折射率的变化敏感。本章将展示如何利用这种现象来创建传感设备。描述了基于表面等离子体的光学传感器（通常称为表面等离子体共振 (SPR) 传感器）的概念，并介绍了 SPR 传感的主要方法。此外，还介绍了亲和生物传感器的概念，并定义了SPR生物传感器的主要性能特点。
In Chap. 1 by J. Homola of this volume [1] surface plasmons were introduced as modes of dielectric/metal planar waveguides and their properties were established. It was demonstrated that the propagation constant of a surface plasmon is sensitive to variations in the refractive index at the surface of a metal film supporting the surface plasmon. In this chapter, it is shown how this phenomenon can be used to create a sensing device. The concept of optical sensors based on surface plasmons, commonly referred as to surface plasmon resonance (SPR) sensors, is described and the main approaches to SPR sensing are presented. In addition, the concept of affinity biosensors is introduced and the main performance characteristics of SPR biosensors are defined.
