Penn Researchers Show New Way of Assembling Particles Into Complex Structures

PHILADELPHIA — Many recent advances in microtechnology and nanotechnology depend on microscopic spherical particles self-assembling into large-scale aggregates to form a relatively limited range of crystalline structures.  Directed assembly is a new branch of this field, where scientists figure out how to make particles assemble to form a broad range of structures at given locations.
