Abstract

The present invention provides a dielectrophoretic device comprising an array (10) of electrodes (1), there being a space (2) in between every two neighboring electrodes (1), and driving means for driving the electrodes (1) of the array (10) to generate a traveling wave dielectrophoretic force. The array (10) of electrodes (1) is formed such that the space (2) in between every two neighboring electrodes (1) has a decreasing width in a longitudinal direction of the electrodes (1). The dielectrophoretic device according to embodiments of the invention can be sued for performing manipulation of particles (5) in small, non-flowing volumes of particles suspensions. The present invention furthermore provides a method for manufacturing such a dielectrophoretic device and a method for manipulating particles (5) by using such a dielectrophoretic device.
