Bienzyme strip-type glucose sensor.
A strip-type glucose biosensor, prepared using screen-printing technology and comprising glucose oxidase (E.C.1.1.3.4.), peroxidase (E.C.1.1.3.13.) and ferrocyanide as mediator incorporated into graphite-hydroxyethyl cellulose matrices is described. The sensor acted at 0.0 V vs Ag/AgCl electrode, and the response time was 50-60 s. The calibration was linear up to 25 mM of glucose. The sensor response was constant in the range of pH 7.0-8.5. At 25 degrees C the biosensor temperature coefficient was 2.7% degrees C(-1). The sensor was insensitive to a physiological level of ascorbic acid (40 microM) and was used for glucose determination in whole blood.
