Abstract

This disclosure relates to an apparatus for glucose-sensing that address interference of ascorbic acid and acetaminophen. The apparatus includes a first electrode capable of oxidizing glucose and at least one of ascorbic acid and acetaminophen. The apparatus further includes a second electrode capable of oxidizing at least one of ascorbic acid and acetaminophen but not capable of oxidizing glucose. The first electrode includes a deposit 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. The deposit is substantially free of a surfactant. If any surfactant is contained in the deposit, the surfactant is in an amount smaller than 0.5 parts by weight with reference to 100 parts by weight of the deposit. The first electrode does not include a glucose-specific enzyme.
