ABSTRACT:
A fluid guide device that can evenly and effectively distribute the potential from a fluid transport source over an area substantially larger than the opening of a source conduit. The fluid guide device includes a first major surface having a structured surface that includes a plurality of flow channels disposed thereon. The flow channels extend from a first point to a second point along the structured surface and have a minimum aspect ratio of about 10:1 and a hydraulic radius no greater than about 300 micrometers (.mu.m). The fluid guide device also includes an active fluid transport source provided external to the structured polymeric surface to provide a potential over the flow channels to promote movement of matter through the flow channels from a first potential to a second potential. The fluid transport source is connected with a plurality of the flow channels of the structured surface by way of a manifold.
