Abstract

This disclosure relates to a glucose-sensing electrode including a nanoporous metal layer and an electrolyte ion-blocking layer formed over the nanoporous metal layer. The nanoporous metal layer is capable of oxidizing both glucose and maltose without an enzyme specific to glucose in the glucose-sensing electrode. The electrolyte ion-blocking layer is configured to inhibit Na+, K+, Ca2+, Cl−, PO43− and CO32− from diffusing toward the nanoporous metal layer such that there is a substantial discontinuity of a combined concentration of Na+, K+, Ca2+, Cl−, PO43− and CO32− between over and below the electrolyte ion-blocking layer.
