英文摘要：

We report on the one-pot preparation of high-performance glucose enzyme electrode through the co-electrode position of o-aminophenol （OAP） polymer and oAP oligomer （oAPO） -Au nanoparticles （AuNPs） - glucose oxidase （GOs） nanoeomposites, which are prepared via the redox reaction of HAuCl4 and oAP aqueous solution in the presence of GOx. The as-prepared biosensor is several folds enhanced in the sensitivity and one-magnitude lowered in the detection limit, as compared with those prepared by the conventional electropolymerization protocol and the similar protocol using K3Fe（CN） 6 as the oxidant. Additionally, the proposed biosensor possesses rapid response, satisfactory anti-interference ability, reproducibility, and storability. The proposed protocol is recommended to prepare other multifunctional nanocomposites and may find wide applications in the biosensing and biomaterials fields.
