Title: MICROFLUIDIC CHIP WITH DIELECTROPHORETIC ELECTRODES EXTENDING IN HYDROPHILIC FLOW PATH
Abstract:
The present invention is notably directed to a microfluidic chip (1, 1a) comprising: a flow path (22) defined by a hydrophilic surface; a liquid input (24, 24a, 24b) on one side of the 4 flow path; at least one electrical circuit (62), hereafter DEP circuit, comprising at least one pair of dielectrophoretic electrodes (E21, E22), hereafter DEP electrodes, wherein: each of the DEP electrodes extends transverse to the flow path; and the DEP circuit is configured to generate a dielectrophoretic force, hereafter DEP force, at the level of the DEP electrodes. 8 The chip may further include one or more electroosmotic circuits. The present invention is further directed to methods of operation of such a microfluidic chip.
