▎ 摘　　要

NOVELTY - Analysis of amphetamine type drug based on artificial molecular recognition system, involves preparing sensor substrate comprising three-electrode system prepared by laser-induced etching of graphene, modifying molecular imprinted polymer film prepared by sol-gel method, washing and demolding to obtain template molecule sensor and evaluating the performance of sensor using differential pulse voltammetry. USE - Analysis of amphetamine type drug based on artificial molecular recognition system for specificity detection. ADVANTAGE - The molecular imprinting film modified electrode can be directly used for specificity detection, independent of large instrument, the detection result has excellent accuracy and reliability, has high specificity and economical, portable, automated, has low detection limit and preparation process is simple.
