Claim Text:
1. An analyte sensor, comprising: a substrate including a core of conductive material and a cladding of a semiconductor material, wherein the cladding is disposed around the core, a protective layer disposed concentrically around, immediately adjacent, and in contact with the substrate, the protective layer including a base layer positioned between a reference electrode and the cladding, wherein an additional layer covers the reference electrode, and a working electrode formed from a portion of the cladding not covered by the protective layer, the working electrode being at least partially coated with an electrochemically-active layer formed from at least one of a noble metal, carbon nanotubes, and a conductive polymer, an active region positioned on the substrate and adapted to be exposed to a fluid environment, the active region including an agent on the electrochemically-active layer on the working electrode.
