Abstract
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.
