DEVICES EXHIBITING DIFFERENTIAL RESISTANCE TO FLOW AND METHODS OF THEIR USE

摘要

The invention features microfluidic devices that contain structures that impart differential resistance to a fluid flow. Differential resistance may be generated parallel, e.g., along the length of a channel, or perpendicular to the length of a channel, to the direction of flow in a channel. Devices of the invention provide differential resistance, e.g., under electric-field-driven flow and pressure-driven flow.
