MICROFLUIDIC DEVICE WITH ELECTRODE STRUCTURES

摘要

The design, development and fabrication of a DEP microfluidic assembly with an in-built interdigitated microelectrode array is presented. Continuous fractionation o f microparticles in a PDMS microfluidic channel is described. Experimental verification of positiv e and negative DEP of yeast cells and polystyrene latex beads is demonstrated. A microfluidic device with DEP arranged electrodes in a channel has posts extending into the channel for controlling shaping of DEP fields.
