Graphene: A Platform for Surface Enhanced Raman Spectroscopy
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.。
