Field-induced Dielectrophoresis and Phase Separation for Manipulating Particles in Microfluidics
Bennett D.J., Khusid B., James C.D., Galambos P.C., Okandan M., Jacqmin D., Kumar A., Qiu Z., Acrivos A., New Jersey Institute of Technology, US
We report observations of new many-body phenomena in the micro-scale behavior of a suspension subject to a high-gradient strong alternating current (ac) field and shear. Their origin is dielectrophoresis accompanied by the field-induced phase separation [...]
Optimal Design of an Electrostatic Zipper Actuator
We describe a method for predicting the optimal design of an electrostatic zipper actuator. The shape of the zipping beam and the electrode are optimized to maximize the applied force at a given stroke, while [...]
Taylor Dispersion in Electroosmotic Flows with Random Zeta Potentials
Electroosmotic flows are extensively employed for fluid transport and sample separation in lab-on-a-chip technologies, capillary zone electrophoresis, and generally in channels and capillaries with length scales on the order of 100 microns or less. Experimental [...]
An Integrated Transport Model for Tracking of Individual Exocytotic Events Using a Microelectrode
A complex biophysical process underlying the release of neurotransmitters and hormones from the secretion cells, known as a vesicular exocytosis, is an important mechanism that defines cell signaling and intercellular communication. This phenomenon has been [...]
The Model of Porous Media – Complete Description for Aggregation of Bead-Monolayers in Flat Microfluidic Chambers
Grumann M., Dobmeier M., Schippers P., Brenner T., Zengerle R., Ducrée J., IMTEK, University of Freiburg, DE
In this paper we for the first time adopt the model of porous media to simulate the complete course of the formation of monolayers from bead suspensions in a flat microfluidic chamber. The chambers are [...]
Dealing with Stiffness in Time-Domain Stokes Flow Simulation
As microfluidic devices become more common and more elaborate, it becomes necessary to develop simulation tools that allow the efficient and yet accurate three dimensional time-domain analysis of the behavior of these devices. Detailed time [...]
Modeling the Fluid Dynamics of Electro-Wetting on Dielectric (EWOD)
By applying voltages across a liquid droplet and an underlying dielectric, it is possible to make dielectric forces compete with surface tension forces, and to thereby cause the liquid droplet to change shape. This effect [...]
