| abstract |
The present invention is notably directed to a microfluidic chip ( 1, 1 a ) comprising: a flow path ( 22 ) defined by a hydrophilic surface; a liquid input ( 24, 24 a, 24 b ) on one side of the flow path; at least one electrical circuit ( 62 ), hereafter DEP circuit, comprising at least one pair of dielectrophoretic electrodes (E 21 , E 22 ), 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. 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. |
