Abstract: A dielectrophoretic fractionation device having a channel defining a direction of flow therethrough for the fractionation of particles in a liquid particle suspension is disclosed. The device also has a deflector unit affixed to a wall of the channel and arranged to generate an electric field gradient in the channel to spatially separate the particles in the liquid particle suspension. The device also has an actuator mounted to the channel and positioned to deform the wall. Also provided is a method for inhibiting aggregation of particles in a liquid particle suspension of the dielectrophoretic fractionation device, the method including periodically deforming the wall with the actuator.
