The bimolecular rate constants for the reactions of five organic two-electron redox mediators with reduced glucose oxidase (GOx) were determined by measuring voltammetric electrocatalytic currents at glassy carbon electrodes in the presence of excess glucose under anaerobic conditions. The mediators
