adding function, self-assembled colloidal nanostructures

Abstract:
Colloidal self-assembly has long been proposed as a pathway to large area periodic structures, however, for many applications, simple self-assembled periodic structures are not sufficient. It remains unclear how to add function to such structures in an efficient fashion, be this introduction of aperiodic features, functional materials, or active components. Here I will discuss our latest results on the use of DNA-directed assembly, electrochemistry, and optical patterning to break periodicity and to form structures not normally accessible through self-organization. I will include in my presentation a discussion of how we convert what are often soft materials to thermally stable robust structures. One clear application for large area optically active structures where robust structures containing both periodic and aperiodic structures will be of interest is solar energy harvesting, and significant strides are being made in this direction.
