中文摘要：
多环芳烃（polycyclicaromatichydrocarbons，PAHs）是一类致癌性很强的环境污染物。由于PAHs分子不含有能与金属配位或键合的官能团，因此很难利用SERS技术对其进行直接检测。本文综述了近年来表面增强拉曼散射（surface-enhancedRama：：scattering，SERS）光谱在PAHs检测方面的应用和研究进展。并着重介绍最近发展成果，利用分子识别技术对贵金属表面进行修饰，使得利用SERS方法对PAHs进行定性鉴别以及定量的检测成为可能。该方法有望在其他类似体系中应用，为低含量有机污染物的检测提供了一个新的有力工具。
英文摘要：
In the present review article, the methodology and recent advances of surface-enhanced Raman scattering （SERS） were described in detection of polycyclic aromatic hydrocarbons （PAHs）. PAHs, a series of organic compounds, are of much concern because some of them as pollutants have been identified as carcinogenic, mutagenic and teratogenic compounds. They show low affinity to metallic surface, which confines applications of SERS to their detections. This article reviewed the develop- ment trends in PAHs analysis by using of SERS substrate modified by supramolecular system. And perspective SERS in PAHs studies have also been presented.
