| Summary: | A novel nonenzymatic glucose sensor was developed based on well-dispersed gold nanoparticles, which were in situ
grown under direction of protein on a reduced graphene oxide modified electrode. This electrode exhibited high
electrocatalytic activity towards glucose oxidation without use of any enzyme or mediator. In application for the
amperometric detection of glucose, a wide linear range of 0.02–16.6 mM, low detection limit of 5 mM and good selectivity
were obtained. The attractive analytical performances of the proposed glucose sensor, coupled with the
facile preparation method, provide a promising electrochemical platform for the development of effective nonenzymatic
sensors. |
