In this paper we review some metasurfaces with negative values of effective refractive index, as scaffolds for a new generation of surface plasmon polariton-based biological or chemical sensors. The electromagnetic properties of a metasurface may be tuned by its full immersion into analyte, or by the adsorption of a thin layer on it, both of which change its properties as a plasmonic guide. We consider various simple forms of plasmonic crystals suitable for this purpose. We start with the basic case of a freestanding, electromagnetically symmetrical plasmonic slab and analyze different ultrathin, multilayer structures, to finally consider some two-dimensional "wallpaper" geometries like split ring resonator arrays and fishnet structures. A part of the text is dedicated to the possibility of multifunctionalization where a metasurface structure is simultaneously utilized both for sensing and for selectivity enhancement. Finally we give an overview of surface-bound intrinsic electromagnetic noise phenomena that limits the ultimate performance of a metasurfaces sensor.
在本文中，我们回顾了一些有效折射率为负值的超表面，作为新一代基于表面等离激元极化激元的生物或化学传感器的支架。超表面的电磁特性可以通过将其完全浸入分析物中，或通过在其上吸附一层薄膜来调节，这两种方式都会改变其作为等离子体波导的特性。我们考虑了适用于此目的的各种简单形式的等离子体晶体。我们从独立的、电磁对称的等离子体平板的基本情况开始，分析不同的超薄多层结构，最后考虑一些二维“壁纸”几何结构，如裂环谐振器阵列和渔网结构。文本的一部分致力于多功能化的可能性，即超表面结构同时用于传感和选择性增强。最后，我们概述了限制超表面传感器最终性能的表面束缚固有电磁噪声现象。
