Abstract

The invention provides a preparation method of a silver fractal and graphene combined plasmon composite structure substrate. The preparation method comprises the following steps: preparing a silver fractal structure on one side of a preset substrate by using an electrochemical deposition method; transferring the single-layer graphene to one side of the silver fractal on the preset substrate by using a wet chemical transfer method; soaking a preset substrate in a preset probe molecule solution, and depositing preset probe molecules on the surface of the preset substrate. According to the application, silver fractal nanostructure is combined with single-layer graphene, the composite structure substrate is obtained, and due to the fact that the silver fractal nanostructure has rich hot spots and self-similarity, Raman signals of probe molecules on the surface of the substrate can be effectively increased, the silver fractal is used as the composite structure substrate, the effect of the Raman signals is greatly enhanced, the preparation process is simple, and the prepared composite structure substrate has high surface enhanced Raman scattering activity.

Description

technical field [0001] This application relates to the field of preparation of optical detection structures, and specifically sets up a preparation method of a plasmonic composite structure substrate combined with silver fractal and graphene. Background technique [0002] Due to its rapidity, in-situ, non-invasive and other advantages, Raman spectroscopy has been widely used in the fields of physics, chemical detection, biosensing and medicine, and has important application value in single-molecule detection and molecular-specific fingerprint identification. . After decades of development, there are more and more researches on surface-enhanced Raman scattering, and its enhancement mechanism is gradually known to everyone, which are electromagnetic enhancement mechanism and chemical enhancement mechanism. The electromagnetic enhancement mechanism believes that when the frequency of the incident light is consistent with the collective oscillation frequency of the local plasmo...
