Abstract:

Surface enhanced Raman scattering (SERS) imparts Raman spectroscopy the capability of detecting analytes at the single molecule level, but the cost is also manifold, such as loss on signal reproducibility. Despite remarkable steps have been taken forward, presently SERS still seems too young to shoulder the analytical missions in various practical situations. By the virtue of its unique molecular structure and physical/chemical properties, the rise of graphene opens up a unique platform for SERS study. 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.
