Manipulating cells on magnetic circuit boards

A circuit board of magnetic pathways has enable precise manipulation of magnetic particles and magnetic-nanoparticle-labeled cells in fluidic environments upon application of a rotating magnetic field.  The trajectory of particles was programmable with conducting lines integrated into the circuit board which allowed transportation of particles from one pathway to another. The device had a multiplexed design to facilitate massively parallel single cell operations such as cell sorting, experimentation and retrieval.
