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.
