Abstract
A device for manipulating magnetic particles, and the method of fabricating and use thereof. The device includes a substrate; a conductive element formed onto the substrate in a pattern shaped to enhance a magnetic field generated in response to an applied current; an insulating layer to isolate the conductive element from a magnetic element; and a magnetic element formed onto the insulating layer to enhance a magnetic force resulting from the magnetic field generated by the conductive element. The magnetic element can be shaped similarly to the conductive element, and edges of the magnetic element are substantially aligned with edges of the conductive element. During fabrication, the substrate and the conductive element can be heated to cause the substrate to shrink thereby resulting in a wrinkled structure at the conductive element. The device can be used to manipulate the magnetic particles within a biological sample, such as cells and/or biomolecules.
