摘要	Metal free material melamine modified graphene oxide (MGO) was prepared by reacting melamine with graphene oxide followed by thermal annealing process. The prepared material was characterized by a range of microscopic and spectroscopic techniques. It was then applied for the detection of epinephrine at a biological pH. An MGO-modified GCE displayed improved electrocatalytic activity by shifting the anodic peak current negatively by 0.1193 V and the cathodic peak current positively by -0.2311 V, compared to those at the GCE. Density Functional Theory (TD-DFT method) was used to predict the electron transfer (ET) sites of MGO. The limit of detection of melamine at the MGO -modified glassy carbon electrode was estimated to be 0.13 mu M which indicated the potential application of the electrode to the biosensing of the neurotransmitter epinephrine.
