An electrochemical sensor electrode strip that measures analyte concentration in an aqueous sample as small as 2.5 to 2.0 mu L is described. Reduction in the minimum sample size is achieved by means of a dielectric coating impregnated into peripheral regions of one or more hydrophilic mesh layers, thereby reducing sample dead volume. The mesh layers are located between an electrode support and a cover layer, which cover layer includes an aperture located upstream from an electrode arrangement. |
