Oxidation Of Glucose

A nonenzymatic electrochemical sensor was fabricated for glucose detection based on gold nanoparticles graphene/carbon nanotube nanohybrids (AuNPs-GH/CNT), which were synthesized through in situ reduction procedure. Cyclic voltammetry (CV) and amperometry were used to evaluate the catalytic activity of the AuNPs-GH/CNT-Nafion modified electrode towards glucose. It was founded that AuNPs-GH/CNT-Nafion modified electrode showed remarkable enhanced electrocatalytic activity towards the oxidation of glucose under optimized conditions. The sensors exhibited linear behavior in the concentration range from 5 μM to 1 mM for the quantification of glucose with a limit of detection of 1.5 μM.
