Embodiment 1
[0027] This example provides a preparation method and application of a fluorescent imprinting material enriched with trace amounts of carboxymethyllysine, including the following steps:
[0028] 1) Precursor preparation of carboxymethyllysine fluorescent imprinting material: 180 mL of Triton X-100 and 7.5 mL of cyclohexane were magnetically stirred at room temperature for 15 minutes, and 3 mg of CdSe / ZnS quantum dots were added. Add 50 μL of tetraethoxysilane and 100 μL of 25% ammonia solution and continue stirring for 2 h. Add 19 μL of 3-aminopropyltriethoxysilane, 100 μL of an aqueous solution of carboxylated graphene at a concentration of 2 mg / mL, 0.4 mg of the template molecule carboxymethyllysine, seal it, and stir at room temperature 20 hours. After the polymerization reaction, first wash the prepared product with acetone, perform centrifugation, remove the supernatant, redisperse it in deionized water, perform centrifugation again, and remove the supernatant again to o...
