Design of multiple constriction ratio microfluidic channels for 3D insulator based dielectrophoretic chips

Insulator based dielectrophoresis (iDEP) is a technique used for sorting microparticles based on their electrical properties which proves to be promising in its development. Using multiple constrictions of area to generate gradients of electric fields allows a device to be made without electrode arrays and at a cheaper cost. The possibility of making devices with multiple constrictions within them is undertaken using micromachining and adhesion methods. The micromachining of multiple constrictions is planned out but further work is needed for optimization. A concept for a commercial device is proposed for low cost fabrication of 3D iDEP devices.
