The present invention is generally directed to a system for controlling
placement of nanoparticles, and methods of using same. In one
illustrative embodiment, the device includes a substrate and a plurality
of funnels in the substrate, wherein each of the funnels comprises an
inlet opening and an elongated, rectangular shaped outlet opening. In one
illustrative embodiment, the method includes creating a dusty plasma
comprising a plurality of carbon nanotubes, positioning a mask between
the dusty plasma and a desired target for the carbon nanotubes, the mask
having a plurality of openings extending therethrough, and extinguishing
the dusty plasma to thereby allow at least some of the carbon nanotubes
in the dusty plasma to pass through at least some of the plurality of
openings in the mask and land on the target.
