▎ 摘　　要

NOVELTY - A copper oxide-nitrogen-doped graphene aerogel modified electrode preparing method involves ultrasonically dispersing copper oxide-nitrogen-doped graphene aerogel in ultrapure water to obtain dispersion liquid. The dispersion liquid is coated on electrode by dropping, and dried at room temperature to obtain the copper oxide-nitrogen-doped graphene aerogel modified electrode. USE - Method for preparing copper oxide-nitrogen-doped graphene aerogel modified electrode for electrochemical glucose detection (claimed). ADVANTAGE - The method enables preparing the modified electrode with enhanced capacity of resisting disturbance, wide detection range and low sensitivity. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for an application of copper oxide-nitrogen-doped graphene aerogel modified electrode for electrochemical glucose detection.
