Résumé : | Horseradish peroxidase and the substrate 3,3',5,5'-tetramethylbenzidine have been incorporated into a solid carbon paste electrode for the development of a H 2O 2 probe. The electrode exhibited a detection limit of 10 -8 mol/L H 2O 2 and a linearity extended over three orders of magnitude. Glucose oxidase was then used in the paste or covalently immobilized onto a preactivated membrane for the detection of glucose. Using both immobilization procedures the measurement of glucose in the micromolar range and an extended linearity was achieved. |
