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.
