Embodiment 1
[0030] The pretreatment method of the glass slides is to ultrasonically clean the slides in deionized water, ethanol, acetone, chloroform, acetone, ethanol, and deionized water for 5 minutes, and then immerse the cleaned slides in hydrogen peroxide and concentrated sulfuric acid. (The volume ratio of hydrogen peroxide and concentrated sulfuric acid is 3:7), heated until no bubbles are generated, and after natural cooling, take out the glass slide, rinse it repeatedly with deionized water, and dry it with nitrogen gas for later use.
[0031] The pretreated glass slide was immersed in 0.5% PDDA aqueous solution for 30 minutes, washed three times with deionized water and dried with nitrogen, and then immersed in the prepared gold sol for 10 hours. The method was deposited on the surface of a glass slide, and finally washed three times with deionized water and dried with nitrogen to obtain a SERS substrate.

Embodiment 2
[0036] The pretreatment method of the glass slides is to ultrasonically clean the slides in deionized water, ethanol, acetone, chloroform, acetone, ethanol, and deionized water for 5 minutes, and then immerse the cleaned slides in hydrogen peroxide and concentrated sulfuric acid. (The volume ratio of hydrogen peroxide and concentrated sulfuric acid is 3:7), heated until no bubbles are generated, and after natural cooling, take out the glass slide, rinse it repeatedly with deionized water, and dry it with nitrogen gas for later use.
[0037] The pretreated glass slide was immersed in 0.5% mass fraction of PDDA aqueous solution for 30 minutes, washed three times with deionized water and dried with nitrogen, and then immersed in the prepared silver sol for 15 hours. The method was deposited on the surface of a glass slide, and finally washed three times with deionized water and dried with nitrogen to obtain a SERS substrate.

Embodiment 3
[0042] The implementation method is the same as that in Example 1, only changing the gold sol to silver sol can also realize the quantitative detection of potassium ions.
