MICROFLUIDIC DEVICES AND SYSTEMS INCORPORATING COVER LAYERS

摘要

PROBLEM TO BE SOLVED: To provide microfluidic methods and devices that combine the advantages of microfluidics with improved material handling characteristics and reduced costs for manufacturing.

SOLUTION: The present invention provides microfluidic devices 100 that comprise a body structure comprising at least a first microscale channel network 114 disposed therein. The body structure has a plurality of ports 106 disposed in the body structure, where each port is in fluid communication with one or more channels in the first channel network. The devices also include a cover layer comprising a plurality of apertures disposed through the cover layer. The cover layer is mated with the body structure whereby each of the apertures is aligned with a separate one of the plurality of ports. The devices also optionally include conductive coatings and membranes. The invention additionally provides methods of controlling the delivery of a composition of material into the microfluidic device 100.
