Magnetophoretic Conductors and Diodes in a 3D Magnetic Field.
This engineering study demonstrates magnetophoretic track designs that transport single magnetized beads and magnetically labeled single cells in a 3D time-varying magnetic field. A vertical field bias is reported to reduce particle clustering but necessitates redesigned track geometries with alternating curvature. The work also demonstrates bidirectional versus unidirectional transport and mentions biological applications including single-cell transport and size-based particle separation.
Key points
- Demonstrates magnetophoretic conductor tracks for transporting single magnetized beads and magnetically labeled single cells.
- Reports that adding a vertical magnetic field bias reduces attraction between particles and inhibits clustering.
- States that effective soft-magnetic track geometries require alternating sections of positive and negative curvature.
- Finds a drop-shape pattern to be more adept at transporting small magnetic beads and single cells than previously studied patterns.
- Shows symmetric patterns can enable bidirectional transport, while asymmetric patterns can enable unidirectional transport.
- Frames these transport behaviors as circuit analogs of a conductor and a diode.
- Demonstrates applications including single-cell transport and size-based separation of magnetic particles.
