Two-Dimensional Programmable Manipulation of Magnetic Nanoparticles on-Chip


Researchers from the Nanomagnetism Group at nanoGUNE have developed a novel device 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 differently shaped nanorings and field sequences allows for the remote manipulation of magnetic particles with high precision along any arbitrary pathway on a chip surface.
