Different shapes of gold nanoparticles (NPs) have different enhancement effect in Surface Enhanced Raman Scattering (SERS). The polyhedral Au NPs have multiple angular structures, which show stronger enhancement effect than Au nanoplatelets. In recent years, the research on synthesis and properties of polyhedral Au NPs has attracted much attention.

Surface-enhanced Raman scattering (SERS) is spectroscopic technique with ultra-sensitivity and high selectivity and has attracted great attention because of the potential applications in various fields. P-aminothiophenol (PATP) is often used as SERS probe molecule because it is easy to adsorb on SERS substrates and produce high-quality SERS signals. TiO2 is extensively used as photocatalyst although its photocatalytic efficiency is still needed to be improved.

Article Synopsis
  • The article reviews the methodology and recent advancements in surface-enhanced Raman scattering (SERS) for detecting polycyclic aromatic hydrocarbons (PAHs), which are harmful environmental pollutants linked to cancer and genetic mutations.
  • It highlights the challenge of PAHs having low affinity to metallic surfaces, which limits the effectiveness of traditional SERS applications in detecting these compounds.
  • The review discusses the evolution of SERS substrates modified by supramolecular systems and provides insights into future directions for PAHs analysis using SERS technology.
