Surface-directed boundary flow in microfluidic channels.
Channel geometry combined with surface chemistry enables a stable liquid boundary flow to be attained along the surfaces of a 12 microm diameter hydrophilic glass fiber in a closed semi-elliptical channel. Surface free energies and triangular corners formed by PDMS/glass fiber or OTS/glass fiber surfaces are shown to be responsible for the experimentally observed wetting phenomena and formation...
متن کاملCharacterisation of PMMA microfluidic channels and devices fabricated by hot embossing and sealed by direct bonding
In this study we fabricated a silicon-based stamp with various microchannel arrays, and demonstrated successful replication of the stamp microstructure on poly methyl methacrylate (PMMA) substrates. We used maskless UV lithography for the production of the micro-structured stamp. Thermal imprint lithography was used to fabricate microfeatured fluidic platforms on PMMA substrates, as well as to ...
متن کاملBonding of microfluidic devices fabricated in polycarbonate.
A simple method for bonding polycarbonate, based on controlled exposure of the pieces to vapours of solvents, yields a tight seal and unmodified geometry of the channels.

Flow Focusing in Microfluidic Devices
This paper presents numerical analysis of the hydrodynamic flow focusing in rectangular microchannels. The low Reynolds number pressure driven flow in symmetric system of crossed channels with three inlets and one outlet is investigated. The numerical model is used to elucidate the origin of broadening of the focused flow sheet observed experimentally close to the side walls of the outlet chann...
