Method for surface-enhanced raman spectroscopy identification based on potential enrichment

Abstract

A method for surface-enhanced Raman spectroscopy identification based on potential regulation includes the following steps: S30: adding a solution to be tested to an electrolytic cell; S40: placing nanostructured substrates in the electrolytic cell to serve as an anode and a cathode, respectively; S50: adding an enhancing reagent to the solution to be tested and setting a potential; and S60: after adsorption and enrichment on the nanostructured substrate, measuring a Raman signal. The electrochemical pretreatment method for surface-enhanced Raman spectroscopy identification based on potential regulation provided herein can promote target molecules to be adsorbed onto a substrate, and enables a signal of a target peak to be amplified by ten thousand or even a million folds.
