Example Embodiment

[0014] Example 1

[0015] 1. Treatment of glassy carbon electrode

[0016] Polish the glassy carbon electrode on the polishing cloth with 1.0μm, 0.3μm and 0.05μm alumina powder, then put it in nitric acid with a volume ratio of 1:1 and sonicate for 6min, then put it in absolute ethanol for 6min, and finally Ultrasonic clean with pure water.

[0017] 2. Preparation of mirtazapine molecularly imprinted electrochemical sensor

[0018] Prepare 10ml of 0.5mol / L nickel sulfate aqueous solution with water as solvent, and 50ml of 0.05mol / L salicylic acid solution with N,N-dimethylformamide as solvent, and then take the prepared 10ml nickel sulfate The aqueous solution was added dropwise to the prepared 50ml salicylic acid solution at a rate of 5 drops / sec. During the dropping process, it was stirred vigorously at 3000 rpm, and then reacted in a 100ml hot water kettle at 118°C for 11 hours. After centrifugation to collect the obtained precipitate, wash with N,N-dimethylformamide and absolut...

Abstract

The invention discloses a preparation method of a high-sensitivity mirtazapine molecularly-imprinted electrochemical sensor. The high-sensitivity mirtazapine molecularly-imprinted electrochemical sensor is prepared by taking mirtazapine as template molecules, taking resveratrol as a functional monomer, taking azodiisobutyronitrile as an initiator, taking a nickel-based metal organic framework material as a doping agent and taking isoalantolactone as a crosslinking agent. The analysis method is simple and practical, and the defects of being complex, expensive in equipment and low in sensitivity of an original analysis method are overcome.

Description

technical field [0001] The invention relates to a molecularly imprinted electrochemical sensor, in particular to a preparation method of a high-sensitivity mirtazapine molecularly imprinted electrochemical sensor. Background technique [0002] Mirtazapine (Remeron) is an antidepressant and an antagonist of central presynaptic α2 receptors, which can enhance adrenergic nerve transmission. It simultaneously blocks central 5-HT2 and 5-HT3 receptors: both enantiomers of mirtazapine have antidepressant activity, the L-isomer blocks α2 and 5-HT2 receptors, and the D-isomer blocks 5-HT2 receptors. -HT3 receptors. The antihistamine receptor (H1) properties of mirtazapine act as a sedative. The drug is well tolerated, has almost no anticholinergic effect, and has no effect on the cardiovascular system. Mirtazapine is indicated for depression and is effective for symptoms such as anhedonia, psychomotor depression, poor sleep (early awakening), and weight loss. However, long-term u...
