-Abstract-
Surface enhanced Raman scattering (SERS) is a mature technique to detect the
molecules with high selectivity and sensitivity. However, how to make the SERS signals
repeatable and quantitative, and how to have deeper understanding on the chemical
enhancement mechanism are still big challenges. Recently, graphene, as well as the
other two dimensional materials, was developed to use as a Raman enhancement
substrate, which was demonstrated to be promising to overcome the issues in
conventional SERS substrate. In this talk, the multi-role of graphene played in SERS is
overviewed in turn, including a Raman probe, a substrate, an additive and a building
block of a flat surface for SERS. Apart from versatile improvements on the SERS
performance towards applications, graphene-involved SERS studies are also expected to
shed light on the fundamental mechanism of SERS effect.
