Abstract:
A device for use in the electrochemical analysis of an analyte in a liquid sample, which comprises:a non-conducting substrate; a discontinuous conductive layer deposited on adjacent first and second portions, respectively, of the non-conducting substrate and defining a non-conducting gap between the first and second portions; an analyte-specific reagent coated on the conductive layer on the first portion; a reference electrode on the the conductive layer on the second portion; a spacer layer deposited over the conductive layer; a monofilament mesh coated with a surfactant or chaotropic agent, the mesh being laid over the analyte-specific reagent, the reference electrode and the spacer layer; and a second non-conductive layer, adhered to and covering the mesh layer, said second non-conducting layer having an exterior edge such that the second non-conducting layer is not co-extensive with the mesh layer, thereby providing an exposed portion of the mesh at one exterior edge of the mesh.
