The present invention relates to microfluidic devices that comprise a 3-D microfluidic network of microchannels of arbitrary complexity and to a method for fabricating such devices. In particular, the invention relates to a method of forming microfluidic devices having 3-D microfluidic networks that contain open or closed loop microchannels using a single-step molding process without the need for layer-by-layer fabrication, and to the resultant microfluidic devices. The networks of such microfluidic devices may comprise one or more microchannel circuits which may be discrete or interconnected.

Microfluidic devices and methods of fabrication

A method is provided for the fabrication of a fibrous structure. Fibers are deposited in a hopper connected to an electrode. A mesh covers the hopper opening and the hopper is inverted and suspended over an adhesive coated substrate. An electric field is generated between the hopper and the substrate while the hopper is simultaneously shaken. As a result, fibers fall through the mesh, aligned along the electric field lines, travel through the electric field, and are coupled on one end thereof to the adhesive.
