GLUCOSE-SENSING ELECTRODE AND DEVICE WITH NANOPOROUS LAYER
First Claim
1. A glucose-sensing electrode comprising:
- at least one electrically conductive layer comprising a surface; and
a nanoporous layer formed on the surfacewherein the nanoporous layer comprises a three-dimensional interconnected network of irregularly shaped bodies that are formed of numerous nanoparticles having a generally oval or spherical shape with a length ranging between about 2 nm and about 5 nm,wherein, inside the three-dimensional interconnected network of irregularly shaped bodies, at least part of the nanoparticles are adjacent to each other without an intervening nanoparticle therebetween and apart from each other to define interparticular nanopores therebetween, wherein at least part of the interparticular nanopores inside the three-dimensional interconnected network of irregularly shaped bodies are in a size ranging between about 0.5 nm and about 3 nm,wherein the nanoporous layer further comprises a three-dimensional interconnected network of irregularly shaped spaces that is geometrically complementary to the three-dimensional interconnected network of irregularly shaped bodies,wherein the glucose-sensing electrode does not comprise a glucose-specific enzyme,wherein the nanoporous layer is substantially free of a surfactant, wherein if any surfactant is contained in the nanoporous layer, the surfactant is in an amount smaller than 0.5 parts by weight with reference to 100 parts by weight of the deposit.

Abstract
This disclosure relates to a glucose-sensing electrode including a nanoporous layer on an electrically conductive surface. The nanoporous layer includes a three-dimensional interconnected network of irregularly shaped bodies that are formed of numerous nanoparticles having a generally oval or spherical shape with a length ranging between about 2 nm and about 5 nm. Inside the three-dimensional interconnected network of irregularly shaped bodies, at least part of the nanoparticles are adjacent to each other without an intervening nanoparticle therebetween and apart from each other to define interparticular nanopores therebetween, wherein at least part of the interparticular nanopores inside the three-dimensional interconnected network of irregularly shaped bodies are in a size ranging between about 0.5 nm and about 3 nm. The nanoporous layer further comprises a three-dimensional interconnected network of irregularly shaped spaces that is geometrically complementary to the three-dimensional interconnected network of irregularly shaped bodies. The glucose-sensing electrode does not comprise a glucose-specific enzyme.
