Abstract
Microfluidic device having a plurality of microfluidic channels and corresponding dielectrophoresis (DEP) electrode arrays, each channel arranged to direct fluid over a DEP electrode array such that in use target particles are manipulated by the DEP electrode array. The device also has a first connection point and second connection point for connecting the device to an alternating current source, a first input of each DEP electrode array connected to the first connection point via the first conductor and second input of each DEP electrode array connected to the second connection point via the second conductor. A resistance of the first conductor between the first input of each electrode and the first connection point, and a resistance of the second conductor between the second input of each electrode and the second connection point is substantially at least an order of magnitude less than a total resistance of the connected electrode arrays.
