Embodiment 1

[0036] 1. Preparation of titanium dioxide substrate: Dilute the titanium dioxide aqueous dispersion to a concentration of 5wt%; perform plasma hydrophilic treatment on a clean quartz sheet or high borosilicate heat-resistant glass; add an appropriate amount of titanium dioxide colloidal aqueous solution dropwise to the hydrophilic treated Spin-coat at 3000rpm for 0.5min on the glass slide substrate. After the spin coating is completed, it is dried and calcined at 450° C. for 1 hour to obtain a titanium dioxide substrate.

Abstract

The invention discloses a preparation method for a high-flux non-continuous dehumidified micropattern substrate. The preparation method comprises the following steps: 1) preparation of a titanium dioxide substrate; 2) subjecting the titanium dioxide substrate to surface hydrophobic treatment so as to prepare a hydrophobic coating; and 3) depositing metal particles onto the surface of the titanium dioxide substrate covered with the hydrophobic coating and cleaning and drying the substrate so as to obtain the high-flux non-continuous dehumidified micropattern substrate. According to the invention, the non-continuous dehumidified micropattern substrate with surface enhanced Raman scattering effect can be prepared in one step by controlling ultraviolet irradiation and is applied to surface enhanced Raman scattering detection; and the preparation method is simple in process, low in cost and convenient for large-scale production.

Description

technical field [0001] The invention relates to a preparation method of a high-throughput discontinuous dehumidification micro-pattern substrate, which belongs to the technical field of analysis and detection. Background technique [0002] Raman spectroscopy is a light scattering phenomenon discovered by Indian scientist C.V.Raman in 1928. It is precisely because of C.V.Raman's contribution to Raman spectroscopy that he won the Nobel Prize in Physics in 1930 and was the first person in Asia to win the Nobel Prize. Compared with other spectroscopic techniques, the detection of Raman spectroscopy has many unique advantages. First of all, Raman spectroscopy has the ability of "fingerprint" identification. at 10-4000cm -1 Within the wavenumber range, it can well match the composition and structure of the substance to be detected, and has strong specificity; secondly, the samples detected by Raman do not need special treatment, and the detection is not interfered by the shape ...
