1. An apparatus suitable for use in measuring blood glucose concentration in a living being using glucose which is present at the buccal mucosal surface of said being, said apparatus comprising:

  • membrane means for containing glucose oxidase enzyme;

    means for positioning the said membrane means against said buccal mucosal surface;

    means for providing oxygen for said membrane means, said provided oxygen used for peroxidative oxidation of said glucose when said membrane means is positioned against said mucosal surface, said oxidation yielding hydrogen peroxide as a product; and

    means for measuring in said membrane means changes in the concentration of at least one compound selected from the group including said provided oxygen and said hydrogen peroxide product.
