Embodiment 1
[0024] In order to further verify the sensitivity of the detection method prepared by the present invention to the detection of mycotoxins in food, examples of the present invention, taking aflatoxin B1 as an example, the specific operation steps are as follows:
[0025] Step 1) Preparation of gold nanotriangles: a three-step gold seed induction method is used to synthesize gold nanotriangles, specifically:
[0026] Gold Seed Solution 1:
[0027] 25 μL of 0.05M HAuCl 4 The solution was added to 4.7 mL, 0.1 M CTAC solution, and 300 μL of freshly prepared 0.01 M NaBH was added under vigorous stirring. 4 solution, put it at room temperature for 3h to remove excess NaBH 4 ;
[0028] Gold Seed Solution 2:
[0029] Dilute 1.6mL, 0.1M CTAC solution with 8mL ultrapure water, add 40μL, 0.05M HAuCl 4 Solution, quickly add 0.01M, 15μL sodium iodide solution;
[0030] Growth solution: 1 mL of 0.05M HAuCl 4 Add the solution to 80mL, 0.05M CTAC solution, and quickly add 0.01M, 600μL ...
