Abstract: A method for fabricating a microfluidic device where first and second substantially flat platens are provided. Multiple substantially planar, substantially metal-free, adhesiveless polymer device layers, the device layers including a first cover layer, second cover layer, and at least one stencil layer defining a microfluidic channel penetrating through the entire thickness of the stencil layer also are provided. Each stencil layer is disposed between other device layers such that the channel is bounded laterally by a stencil layer, and bounded from above and below by surrounding device layers to define an upper channel surface and a lower channel surface. The device layers are stacked between the first platen and the second platen. The stacked device layers are controllably heated according to a heating profile adapted to form a substantially sealed adhesiveless microfluidic device wherein each upper channel surface remains distinct from its corresponding lower channel surface. The resulting microfluidic device has high inter-layer bond strength while preserving the integrity of the channel(s) defined in the stencil layer(s).

Abstract: Microfluidic analytical devices and systems have at least one porous element disposed downstream of one or more optical detection regions in a pressure-based separation system. A porous element elevates the backpressure within an optical detection region, thus suppressing bubble formation and enhancing optical detection. Various types of porous elements include porous membranes, packed particulate material, and polymerized monoliths. Preferred devices may be fabricated with substantially planar device layers, including stencil layers, that are directly bonded without adhesives to form a substantially sealed microstructure suitable for performing pressure-based chromatographic separations at elevated operating pressures and with organic solvents.

Abstract: Microfluidic devices capable of efficiently mixing two or more fluid are provided. Two or more microfluidic inlet channels defined in different sheets of material meet at an overlap region in fluid communication with an outlet channel. The channels are defined through the entire thickness of stencil sheets.

Abstract: Microfluidic devices for splitting an established fluidic flow through a microfluidic channel among multiple downstream microfluidic channels include a plurality of elevated flow resistance regions to promote precise and predictable splitting. Each elevated resistance region imparts a flow resistance that is substantially greater than the characteristic resistance to established flow of its associated downstream channel. Elevated flow resistance regions may include one or more porous materials and/or alterations to the channel geometry of at least a portion of a downstream channel.
