Notes:
In this paper, the behavior of microparticles subjected to the AC electric fields generatedby planar microelectrode systems is studied. Microelectrodes including interdigitated array,castellated array, and jagged array are constructed using microfabrication techniques. Micron-sizedlatex beads are used to study their movements. Positive and negative dielectrophoresis (DEP) arestudied. In the interdigitated electrodes, particles experiencing n-DEP are levitated stably to certainheights where the vertical DEP force is balanced by the gravitational force. The levitation heights ofthe particles are measured using the consecutively focusing method. The results provide significantinstructions for the dielectrophoretic manipulation and separation of bioparticles
