High-throughput precise particle transport at single-particle resolution in a three-dimensional magnetic field for highly sensitive bio-detection.

Precise manipulation of microparticles have fundamental applications in the fields of lab-on-a-chip and biomedical engineering. Here, for the first time, we propose a fully operational microfluidic chip equipped with thin magnetic films composed of straight tracks and bends which precisely transports numerous single-particles in the size range of ~ 2.8-20 µm simultaneously, to certain points, synced with the general external three-axial magnetic field.
