Microstructures: Autonomous Magnetic Microrobots by Navigating Gates for Multiple Biomolecules Delivery (Small 25/2018)

In article number 1800504, Valentine Novosad, CheolGi Kim, and co-workers report a universal micromagnet junction of self-navigating gates for autonomous microrobotic carriers to deliver biomolecules to specific sites using a remote magnetic field. The non-magnetic gap between the lithographically fabricated donor and acceptor micromagnets creates a crucial energy barrier to regulate carrier particle gating. The proposed junctions could lead to a novel lab-on-chip microfluidic platform for the synchronous digital transport, manipulation and sorting of bioconjugated nanoparticles and cells.
