Biosensor and methods of biosensor construction

Abstract

Embodiments provide for an analyte sensors and methods of construction thereof. In one example, a method of constructing an indwelling analyte sensor comprises coating a wire with a dielectric material, removing one or more regions of the dielectric material to expose one or more electrochemically active surface(s), producing a pattern in the one or more exposed electrochemically active surfaces to increase surface area of the one or more electrochemically active surfaces, and coating remaining regions of dielectric material and the one or more exposed electrochemically active surfaces with a membrane material comprising an enzyme layer. In this way, sensor response and performance can be improved with corresponding reductions in in-skin sensor length.
