Abstract
A method to create microfluidic devices by utilizing hot imprinting stamps formed using printed circuit boards is demonstrated. Very large microfluidic devices (15×15 cm2) can be created with lateral features down to 100 microns and depths of nominally 17-70 μm. Room temperature solvent bonding was found to be a simple method of sealing the channels. The work also decribes the fabriation and operation of thermally actuated microvalves with sub-second switching and micropumps based on the imprinting techniques described.
