PROBLEM TO BE SOLVED: To provide a device and method for processing magnetic particles for effective mixing in a fluidic environment, particularly in a microfluidic environment.SOLUTION: A device for manipulating and mixing magnetic particles in a surrounding liquid medium, comprises at least one couple of magnetic poles 1, 1' facing each other across a gap, diverging from a narrow end of the gap to a wide end of the gap, where the magnetic poles with the gap form an electromagnetic circuit and are arranged to provide a magnetic field gradient in the gap region; and a reaction chamber 2 that is a part of a microfluidic network for containing the magnetic particles in suspension and arranged in the gap of the electromagnet poles 1, 1'. The reaction chamber 2 preferably has at least one part which has a diverging cavity, arranged co-divergently in the diverging gap between the poles. |
