Raman spectroscopy is a sensitive method for monitoring the self-assembly of biological macromolecules. Amyloidogenic peptides have been shown to form peptide nanotubes often with a central diphenylalanine core. In this article, we show that UV resonance Raman spectroscopy (UVRR) can be used to characterize nanotubes formed with diphenylalanine (FF) peptides and graphene by tuning the excitation wavelengths to match the electronic transitions of the individual components (FF and graphene) and probe their properties during assembly. Raman spectra of graphene consist of spectral bands indicative of sp(2) hybridized content. Deep UVRR spectra of graphene show a distinct "G" tangential stretching mode, which is split into a doublet at 1477 cm(-1) and 1516 cm(-1). Scanning electron microscopy is used to confirm formation of diphenylalanine-graphene nanotube assembly.
