A typical Raman spectrum of the 1 × 10−5 M R6G solution on copper vanadate nanoribbons as substrate (upper part) and the SERS contour (lower part).

(a) The SERS spectrum of 0.01 M Try solution (pH = 10, NaHCO3-Na2CO3 buffer); (b) The Raman spectrum of 0.01 M Tyr solution (pH = 10, NaHCO3-Na2CO3 buffer), hardly showing a characteristic peak; and (c) schematic of the combination pattern: Tyr and vanadate.
