NOVELTY - The utility model claims a glucose sensor based on three-dimensional graphene, comprising a flexible substrate, a working electrode, a counter electrode, a reference electrode and an insulating layer composed of carbon paste working electrode lead, a carbon paste working electrode and working electrode function layer; the work electrode function layer from bottom to top is composed of a three-dimensional graphene, glucose oxidase, chitosan and glutaraldehyde, the electrode lead by carbon paste and carbon paste electrode, reference electrode of silver wire and a silver/silver chloride electrode. The sensor overcomes the shortcoming of the current conventional lactate sensors, can be economical and environment-friendly, simple and high efficient and quality controlled manner glucose sensor prepared graphene, and graphene nano-wall three-dimensional conductive network structure and large specific surface area effectively increases the sensitivity and real-time of the lactic acid detecting property, at the same time, because the flexible substrate, the sensor can be widely used for medical monitoring and diabetic blood sugar self-management.
