▎ 摘　　要

NOVELTY - Preparation of 3-nitrotyrosine molecular imprinted electrochemical sensor comprises electroporating suspended droplets of multi-walled carbon-coupled graphene nanotubes on surface of glassy carbon electrode; doping obtained multi-walled carbon-coupled graphene nanobelts modified electrode in gold nano-molecular imprinted polymer solution, forming layer of molecularly imprinted polymer containing pyrrole as functional monomer and 3-nitrotyrosine as template molecule; and removing 3-nitrotyrosine template molecule to obtain sensor. USE - Method for preparing 3-nitrotyrosine molecular imprinted electrochemical sensor (claimed). ADVANTAGE - The sensor has high selectivity and sensitivity, simple structure, stable performance, good repeatability, low preparation cost, and fast detection time.
