Abstract

A novel device is designed for on-chip selective trap and two-dimensional remote manipulation of single and multiple fluid-borne magnetic particles using field controlled magnetic domain walls in circular nanostructures. The combination of different ring-shaped nanostructures and field sequences allows for remote manipulation of magnetic particles with high-precision along any arbitrary pathway on a chip surface.
