▎ 摘　　要

NOVELTY - Preparing electrochemical sensor based on the synergistic effect of graphene nano ribbons and gold nanoparticles comprises sequentially modifying graphene nano ribbons and gold nanoparticles onto a glassy carbon electrode through electrodeposition, and using electro polymerization to polymerize the molecularly imprinted membrane on surface of modified electrode. USE - The preparation method of electrochemical sensor is used in detection of corn zearalenone in food. Uses include e.g. gas chromatography, liquid chromatography and tandem mass spectrometry. ADVANTAGE - The sensor has high sensitivity and good selectivity, little time consumption, simple operation, and fast response. The modification of the electrode can increase the specific surface area of electrode and improve the number of recognition sites, and the synergistic effect of the two also can effectively promote the transmission of the electron, further improving the sensitivity of the sensor. DESCRIPTION OF DRAWING(S) - The drawing shows a molecular imprinting film/gold nano particle/reduction oxidation graphene the modified electrode of the preparation flow chart.
