Dielectrophoresis Response and Manipulation of TiO₂ Particles

Abstract:

This paper presents a device to investigate dielectrophoresis (DEP) effects through different patterns of the electrodes. Pattern of electrodes, DEP time and voltage have been described to research the manipulation of particles by dielectrophoresis. The TiO₂ sample droplet was dropped onto several electrode pairs using a micro-dropper. We succeeded in manipulating TiO₂ particles along the electric field and deposited them across the gaps between two electrodes by modulating different factors. SEM images were used to confirm the patterns of different electrodes.
