We present a process for fabricating nanostructured surfaces with feature sizes down to at least 50nm and aspect ratios of 1:1 by injection molding. We explored the effects of mold coatings and injection molding conditions on the final nanostructure
Selective bioparticle retention and characterization in a chip-integrated confocal ultrasonic cavity

We demonstrate selective retention and posi- tioning of cells or other bioparticles by ultrasonic manip- ulation in a microfluidic expansion chamber during microfluidic perfusion. The chamber is designed as a con- focal ultrasonic resonator for maxim

We present a sharp-interface model of two-dimensional ramified growth during quasi-steady electrodeposition. Our model differs from previous modeling methods in that it includes the important effects of extended space-charge regions and nonlinear ele

We present experiments and simulations of magnetic separation of magnetic beads in a microfluidic channel. The separation is obtained by microfabricated electromagnets. The results of our simulations using FEMLAB and Mathematica are compared with exp

We present a capillary flow system for liquid transport in microsystems. Our simple microfluidic system consists of two planar parallel surfaces, separated by spacers. One of the surfaces is entirely hydrophobic, the other mainly hydrophobic, but wit

Possible mechanisms for over-limiting current (OLC) through aqueous ion-exchange membranes (exceeding diffusion limitation) have been debated for half a century. Flows consistent with electro-osmotic instability (EOI) have recently been observed in m

We demonstrate a nanofluidic-based carbon dioxide sensor through corroboration with our nanochannel hydronium-dominated ion transport model. We verify the predictive power of our model by comparing calculated and measured conductances of solutions wi

We present theoretical and experimental studies of the streaming current induced by a pressure-driven flow in long, straight, electrolyte-filled nanochannels. The theoretical work builds on our recent one-dimensional model of electro-osmotic and capi

We describe experimental and theoretical studies dedicated to establishing the physics of formation of double droplets in microfluidic systems. We show that the morphologies (complete engulfing, partial engulfing, and nonengulfing) obtained at late t

We demonstrate and investigate multiple localized ultrasonic manipulation functions in series in microfluidic chips. The manipulation functions are based on spatially separated and confined ultrasonic primary radiation force fields, obtained by local
