Flow-switching microdevice
First Claim
1. A microdevice for controlling fluid flow, comprising:
- a cover plate having a substantially planar contact surface and a plurality of fluid-transporting features associated therewith; and
a substrate having a substantially planar contact surface and a fluid-transporting feature associated therewith, wherein the contact surfaces are positioned in slidable and fluid-tight contact to allow for controllable formation of a plurality of different flow paths upon alignment of the substrate fluid-transporting feature with each cover plate fluid-transporting feature in succession.

Abstract
A microdevice is provided for controlling fluid flow. The microdevice includes a substantially planar contact surface and a plurality of fluid-transporting features associated therewith. Also included is a substrate having a substantially planar contact surface and a fluid-transporting feature associated therewith. The contact surfaces are positioned in slidable and fluid-tight contact to allow for controllable formation of a plurality of different flow paths upon alignment of the substrate fluid-transporting feature with each cover plate fluid-transporting features in succession. Typically, at least one of the cover plate and substrate is comprised of a biofouling resistant polymer, and the flow paths are of different lengths. Optionally, a plurality of fluid-transporting features is associated with the substrate so that flow paths are formed as a result of a different alignment of the fluid-transporting features.
