A glucose sensor utilising tetracyanoquinodimethane as a mediator.
This paper describes an amperometric enzyme electrode for glucose analysis. The electrode utilised the mediator tetracyanoquinodimethane (TCNQ) to facilitate electron transfer from glucose oxidase to a pyrolytic graphite carbon electrode. The electrode demonstrated a response to glucose in a clinically relevant range (0-70 mM). Results concerning the direct current cyclic voltammetry of TCNQ and the electrodes' response to glucose, pH profile and the effect of temperature are presented.
