Picture of the day


Heinrich Jaeger and Ward Lopes, Nanochain

False-color transmission electron microscope image of self-assembled gold nanochains produced at the University of Chicago. The center-to-center spacing between neighboring chains measures 50 nanometers. Individual gold nanoparticles measure 5 to 10 nanometers and self-assemble inside the polystyrene domains of a thin copolymer film. Polymethylmethacrylate domains of the film, on either side of the chains, do not contain nanoparticles and appear dark. (click to see full sized version)
