Devices for manipulating magnetic particles, and methods of fabricating the devices and the use thereof

A device for manipulating magnetic particles, the device comprising:

• a substrate;
• a conductive element formed onto the substrate in a meandering design pattern shaped to enhance a magnetic field generated in response to a current applied to the conductive element, the conductive element including one of a microstructure having a high aspect ratio and a nanostructure having a high aspect ratio;
• an insulating layer;
• and
• a magnetic element formed onto the insulating layer, the magnetic element is shaped in the design pattern, and edges of the magnetic element are substantially aligned with corresponding edges of the conductive element, and the insulating layer isolates the conductive element from the magnetic element, and the magnetic element enhances a magnetic force resulting from the magnetic field generated by the conductive element.
