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.
Claims20
A method of making a nanoporous layer, the method comprising:
- dispensing on a substrate a colloid composition comprising a liquid and a number of nanoparticle clusters, wherein each nanoparticle cluster comprises a number of nanoparticles;
- and
- subjecting the dispensed colloid composition to drying to cause nanoparticle clusters to get close to one another and settle over the substrate as the liquid dries off, which deposits irregularly shaped bodies comprising nanoparticles to form a nanoporous layer over the substrate,
- wherein the irregularly shaped bodies are connected to one another to provide a three-dimensional interconnected network of irregularly shaped bodies in the nanoporous layer.
