Abstract
Particles having a non-uniform property, such as non-uniform charge, can be used to form complex yet controlled particle assemblies. In one method of fabrication, particles are located on a substrate, and a surface treatment applied to the exposed portion of the particle surface. The surface treatment modifies the particle properties within the exposed portion. One or more lithographed regions are not exposed to the surface treatment, providing spatial selectivity in inter-particle bonding after the particles are removed from the substrate.
