Abstract
Apparatus and method for manipulating particles on a micro- or nano-scale. An embodiment of the present invention includes a magnetic micro-manipulation technique that utilizes micro-coils and soft magnetic microscopic wires for localized manipulation of particles. Another embodiment of the present invention uses magneto-static interaction between two magnetic microscopic wires to mechanically manipulate particles. Yet another embodiment of the present invention combines a magnetic particle with a magnetic manipulator or other device for generating magnetic fields to operate as a micro-fluidic micro-motor. Other embodiments of the present invention employ a magnetic separation system employing porous membranes partially filled with magnetic wires.
