Molecules self-assemble into stripes

Abstract:
Now, a team led by Johannes Barth at the University of British Columbia in Vancouver have developed a new "bottom up" approach, whereby molecules of the amino acid "methionine" assemble themselves onto silver surfaces. To create the nanostructures, the physicists prepared a highly regular surface of silver by heating and rapidly cooling it. They then deposited a beam of methionine onto the substrate, and observed as the molecules formed periodic stripes on the substrate.
