Liquid dielectrophoresis on the microscale
Polarizable liquids respond to a non-uniform electric "eld by collecting preferentially in regions of maximum "eld intensity. This manifestation of dielectrophoresis (DEP) is a wellknown example of the ponderomotive force, with the "eld acting on individual (molecular) dipoles in the liquid. When electrode dimensions are scaled down to &10 to 100 m, liquid DEP makes possible a new type of high-...
متن کاملLocal Surface Modification at the Microscale Enabled by Liquid Dielectrophoresis Technology
This paper reports a new protocol on-chip for functionalization purpose enabled by liquid dielectrophoresis (LDEP) technique at the microscale, and its adaptation to the nanoscale for the MEMS/NEMS applications. In a previous study, circular spots (diameter: 25-100 μm), made of polymer, have been accurately positioned onto a surface using LDEP. In this study, doped polysilicon LDEP structures h...
متن کاملMicroscale liquid phase separations.
Miniaturization and microfabrication of analytical instrumentation for chemical and biological analyses has been proceeding at a rapid pace for a few decades, and has gained momentum in the past decade with the introduction and application of microfabricated instruments. Motivating factors for performing microscale separations and analyses are reduced reagent, solvent and sample consumption, re...
متن کاملCapillarity and dielectrophoresis of liquid deuterium
The ponderomotive force, exerted upon all dielectric liquids by a non-uniform electric field, can be used for the remote, voltage-controlled manipulation of 10 to 100μL volumes of cryogenic liquids. This liquid dielectrophoretic (DEP) effect, imposed by specially designed electrodes, combines with capillarity to influence the hydrostatic equilibria of liquid deuterium. A simple, one-dimensional...
متن کاملMicroscale locomotion in a nematic liquid crystal.
Microorganisms often encounter anisotropy, for example in mucus and biofilms. We study how anisotropy and elasticity of the ambient fluid affects the speed of a swimming microorganism with a prescribed stroke. Motivated by recent experiments on swimming bacteria in anisotropic environments, we extend a classical model for swimming microorganisms, the Taylor swimming sheet, actuated by small-amp...
