Golden potential for gold thin films
Date:4/27/2012

Scientists with the Lawrence Berkeley National Laboratory (Berkeley Lab) and the University of California (UC) Berkeley have directed the first self-assembly of nanoparticles into device-ready materials. Through a relatively easy and inexpensive technique based on blending nanoparticles with block co-polymer supramolecules, the researchers produced multiple-layers of thin films from highly ordered one-, two- and three-dimensional arrays of gold nanoparticles. Thin films such as these have potential applications for a wide range of fields, including computer memory storage, energy harvesting, energy storage, remote-sensing, catalysis, light management and the emerging new field of plasmonics.

"We've demonstrated a simple yet versatile supramolecular approach to control the 3-D spatial organization of nanoparticles with single particle precision over macroscopic distances in thin films," says polymer scientist Ting Xu, who led this research. "While the thin gold films we made were wafer-sized, the technique can easily produce much larger films, and it can be used on nanoparticles of many other materials besides gold."

Xu holds joint appointments with Berkeley Lab's Materials Sciences Division and UC Berkeley's Departments of Materials Sciences and Engineering, and Chemistry. She is the corresponding author of a paper describing this research in the journal Nano Letters titled "Nanoparticle Assemblies in Thin Films of Supramolecular Nanocomposites." Co-authoring the paper were Joseph Kao, Peter Bai, Vivian Chuang, Zhang Jiang and Peter Ercius.

Nanoparticles can be thought of as artificial atoms with unique optical, electrical and mechanical properties. If nanoparticles can be coaxed into routinely assembling themselves into complex structures and hierarchical patterns, similar to what nature does with proteins, devices a thousand times smaller than those of today's microtechnologies could be mass-produced.
