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 development trends in PAHs analysis by using of SERS substrate modified by supramolecular system. And perspective SERS in PAHs studies have also been presented.
