Surface enhanced Raman scattering (SERS) is undergoing a renaissance, spurred largely by developments in the burgeoning field of plasmonics. This paper reviews the current status and future directions in plasmonic nanostructures for SERS. We show that engineered plasmonic nanostructures enable exciting new functionalities, including beamed Raman scattering and highly reproducible chips for single molecule SERS. We furthermore show that silicon photonics enables SERS to be performed using optically trapped Ag nanoparticle clusters.
