Surface-enhanced infrared absorption (SEIRA) has attracted increasing attention due to the potential of infrared spectroscopy in applications such as molecular trace sensing of solids, polymers, and proteins, specifically fueled by recent substantial developments in infrared plasmonic materials and engineered nanostructures. Here, the significant progress achieved in the past decades is reviewed, along with the current state of the art of SEIRA. In particular, the plasmonic properties of a variety of nanomaterials are discussed (e.g., metals, semiconductors, and graphene) along with their use in the design of efficient SEIRA configurations. To conclude, perspectives on potential applications, including single-molecule detection and in vivo bioassays, are presented.
表面增强红外吸收（SEIRA）由于其在固体、聚合物和蛋白质等分子痕量传感应用中的红外光谱的潜力而受到越来越多的关注，这主要得益于最近在红外等离子体材料和工程纳米结构方面的重大进展。在这里，回顾了过去几十年所取得的重大进展，以及 SEIRA 的现状。特别是，讨论了各种纳米材料的等离子体特性（例如金属、半导体和石墨烯）及其在高效 SEIRA 配置设计中的应用。最后，介绍了潜在应用的展望，包括单分子检测和体内生物测定。
