Graphene-enhanced Raman scattering (GERS) is emerging as an important method due to the need for highly reproducible, quantifiable, and biocompatible active substrates. As a result of its unique two-dimensional carbon structure, graphene provides particularly large enhanced Raman signals for molecules adsorbed on its surface. In this work, the GERS signals of a test molecule, 4-mercaptobenzoic acid (4-MBA), with reproducible enhancement factors are discussed and compared with surface-enhanced Raman scattering (SERS) signals from highly active substrates, covered with spherical silver nanoparticles. It is shown that chemical interactions between the molecule and graphene can result in a frequency shift in the graphene-enhanced Raman signal of the molecule.
