Abstract

The invention discloses a preparation method of a surface-enhanced Raman scattering substrate. The preparation method comprises the following steps of: (1) preparing a flexible nano imprinting template with patterns and in a double-layer composite structure; (2) imprinting ordered nano structure patterns; (3) carrying out vacuum evaporation; and (4) eliminating a nano imprinting gel baffle layer. The preparation method can be applied to preparation of all surface-enhanced Raman scattering substrates; the defects that the substrate is strictly required in preparing the SERS (Surface-Enhanced Raman Scattering) substrate in the conventional nano imprinting mode, and metal ordered structure SERS substrates with high resolution are hard to be prepared on complex appearance and high-curvature surfaces are overcome; and moreover the method is simple in process, can be used for producing high-performance SERS substrates with large area, large scale and low cost, can solve the preparation requirements of the SERS substrates and can meet the present practical requirements well.

Description

technical field

[0001] The invention relates to the technical field of surface spectroscopy, in particular to a method for preparing a surface-enhanced Raman scattering substrate with an ordered structure. Background technique

[0002] Since Martin Fleischmann first discovered the Surface Enhanced Raman scattering (SERS) phenomenon in the 1970s, after decades of development, SERS detection technology has been widely used in physics, chemistry, biology, medicine, materials, etc. In various fields, it has become an important tool for the trace detection of substance molecules. The preparation of active substrates is the prerequisite for obtaining SERS signals. In order to use SERS as a routine and online analysis tool, the prepared SERS substrates should have high signal enhancement ability and good uniformity, easy preparation and storage, and convenient use. At present, the methods used to prepare SERS active substrates mainly include sol-gel method, electrochemical dep...
