摘要：The present invention relates to a microdevice having a valve structure thatcontains low or no dead volume. The microdevice comprises a substrate and a cover plateeach having a substantially planar contact surface and each contact surface having a fluid-transporting feature associated therewith. The substrate contact surface is positioned in
slidable and fluid-tight contact with the cover plate contact surface to allow forcontrollable alignment between the fluid-transporting features. As a result, fluidcommunication is provided therebetween through a small area. Where the cover platefluid-transporting feature comprises a conduit, the conduit may have a substantiallyconstant cross-sectional area. The controllable alignment between the fluid-transportingfeatures may form an alignment-dependent variable-length flow path.
