Embodiment 1
[0014] 1. Treatment of glassy carbon electrodes
[0015] Polish the glassy carbon electrode on a polishing cloth with 1.0 μm, 0.3 μm and 0.05 μm alumina powder in turn, then put it into nitric acid with a volume ratio of 1:1 for 8 minutes, then put it into absolute ethanol for 8 minutes, and finally Ultrasonic cleaning with pure water.
[0016] 2. Preparation of Meprobamate Molecularly Imprinted Electrochemical Sensor
[0017] To 10.0mL solvent ethanol, add 0.5mmol template molecule meprobamate, 5.0mmol functional monomer aminotadalafil, 3.8mmol crosslinking agent hydrocortisone acetate, 0.1mmol initiator azobis Isobutyronitrile and 0.0250g of dodecanethiol-functionalized gold nanoparticles were ultrasonically dissolved for 12 minutes each time a chemical reagent was added;
[0018] Take 6 μL of the mixture in step and apply it on the surface of a clean and smooth glassy carbon electrode with a diameter of 2 mm. The template molecules were eluted with a mixed solvent of ...
