Abstract
A liquid transport system provides controlled flow of liquid in a liquid flow zone between two surfaces wherein one surface includes a plurality of projections, or raised areas, arranged substantially throughout the surface in the liquid flow zone and an aperture for allowing the introduction of liquid between the two surfaces. In a preferred embodiment the projections on the first surface are arranged in parallel spaced rows and parallel spaced columns. The second surface may be one surface of a layer of a diagnostic assay element.
