Abstract
A device, for use in the electrochemical analysis of an analyte in a small volume liquid sample, having a non-conducting substrate ( ); a conductive layer, deposited on the substrate, in two parts ( ), defining a non-conducting gap ( ) therebetween; an analyte-specific reagent ( ) coated on the conductive layer, on one side of the gap; a reference electrode ( ) on the conductive layer, on the other side of the gap; a spacer layer ( ) deposited over the conductive layer; a monofilament mesh ( ) coated with a surfactant or chaotropic agent, the mesh being laid over the reagent, the reference electrode and the spacer layer; and a second non-conductive layer ( ) adhered to the mesh layer, but not coextensive therewith, thereby providing a sample application area ( ) on the mesh.
