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