Synthetic nanomotors in microchannel networks: directional microchip motion and controlled manipulation of cargo

J Am Chem Soc. 2008 Jul 2;130(26):8164-5. doi: 10.1021/ja803529u. Epub 2008 Jun 6.


We illustrate the use of catalytic nanowire motors for directional motion and microscale transport of cargo within microfluidic channel networks. The CNT-based synthetic nanomotor can propel a large cargo load at high speeds through predetermined paths and junctions of the microchannel network. The magnetic properties of the nickel-containing nanomotors offer controlled cargo manipulations, including en-route load, drag, and release. Such use of synthetic nanomachines can lead to chemically powered versatile laboratory-on-a-chip devices performing a series of tasks simultaneously or sequentially.
