The surface-enhanced Raman scattering for monitoring histidine and tyrosine using silver vanadate nanoribbons as substrates Original Research Article

Silver vanadate nanoribbons were synthesized via a hydrothermal process. These nanoribbons were 20–30 nm in thickness, 200 nm in width, and hundreds of micrometers in length confirmed by scanning electron microscopy. They were also served as the surface-enhanced Raman scattering substrates, which were stable and could monitor histidine and tyrosine easily and rapidly. There was a corresponding relation between the false color plot of Raman intensity and the silver vanadate morphology. And the possible explanations for the action between AgVO3 nanoribbons and these amino acids were proposed. The results might open up new thinking on surface-enhanced Raman scattering using AgVO3 nanoribbons as substrates.
