2D materials coated plasmonic structures for SERS applications

Two-dimensional (2D) materials, such as graphene and hexagonal boron nitride, are new kind of materials that can serve as substrates for surface enhanced Raman spectroscopy (SERS). When combined with traditional metallic plasmonic structures, the hybrid 2D materials/metal SERS platform brings extra benefits, including higher SERS enhancement factors, oxidation protection of metal surface, and protection of molecules from photo-induced damage. This perspective gives an overview of recent progress in 2D materials coated plasmonic structure in SERS application. This paper focuses on the fabrication of the hybrid 2D materials/metal SERS platform and their applications for Raman enhancement.
