nanoparticles and nanowires,
can serve as modular building blocks for integrated nanoscale systems.
We demonstrate a microfluidic approach for positioning, orienting,
and assembling such nanostructures into nanoassemblies. We use flow
control combined with a cross-linking photoresist to position and
immobilize nanostructures in desired positions and orientations. Immobilized
nanostructures can serve as pivots, barriers, and guides for precise
placement of subsequent nanostructures.
