A combined metal and graphene substrate improves the performance of surface-enhanced Raman spectroscopy (SERS), Jin Zhang of Peking University and coworkers report (Proc. Natl. Acad. Sci. USA, DOI: 10.1073/pnas.1205478109). Most SERS substrates have rough metal features that sometimes interact with analytes in a way that can complicate SERS spectra. Zhang and coworkers fabricate their new SERS substrate by depositing an array of . . .
