Microfluidic Gradient Formation by Maxwell-Wagner Polarization at an Aqueous Electric Interface

submitted by: zgagnon
This work integrates components from AC electrokinetics, microfluidics, and cell biology to produce tunable spatial chemical gradients in a microfluidic device for studying directed cell migration. I explore a new type of Maxwell Wagner polarization for the injection of aqueous liquid across a liquid-liquid interface. The rate of injection is tunable and used to manipulate fluid much the same way dielectrophoresis is used on bioparticles; fluid can be injected into different streamlines and...
