Abstract

DEP

IDEP

Particle concentrator

Particle separation

A particle separator was demonstrated based on 3-D insulator-based dielectrophoresis (iDEP). Two droplets containing mixtures of 1-μm and 5-μm polystyrene beads were placed above and beneath a 200-μm-thick PMMA sheet. An array of X-ray lithography fabricated through microholes on the PMMA sheet generated the 3-D iDEP forces since it distorted the electric line passing through. When applying a proper AC signal, 1-μm beads were concentrated and deposited in the microholes, while 5-μm beads were expelled from the microholes by the 3-D iDEP forces. © 2006 Society for Chemistry and Micro-Nano Systems.
