Abstract:
1. A method of manufacturing a collection assembly for use in a glucose sampling system and for electrochemical detection of an amount or concentration of glucose, the method comprising: providing a hydrogel comprising: contacting the first surface of the hydrogel with a mask layer, the mask layer comprising a material that is substantially impermeable to glucose or derivatives thereof, wherein the mask layer (i) has an inner face and an outer face, and the inner face is positioned in facing relationship with the first surface of the hydrogel, and (ii) defines a first opening that exposes at least a portion of the first surface of the hydrogel, and contacting the second surface of the hydrogel with a gel retaining layer, the gel retaining layer comprising an inner face and an outer face, wherein the inner face is positioned in facing relationship with the second surface of the hydrogel, and wherein the gel retaining layer defines a first opening that exposes at least a portion of the second surface of the hydrogel to complete the collection assembly.
