Shape Selectivity in the Assembly of Lithographically Designed Colloidal Particles

摘要

There is an outstanding need for methods with which to form complex,three-dimensional structures on the colloidal scale (10 nm to 10 mu m).Such methods would be valuable for the development of photonics,high-density memory and electronics,and micromechanical devices.An attractive approach to this challenge is to exploit the concepts of chemical thermodynamics to form structure from colloidal particles.This approach,based on self-assembly,requires the development of a diversity of building blocks,selective and directional interactions,and methods of processing.
