University of Chicago physicists pioneer method for nanotechnology fabrication

Nanowire False-color transmission electron microscope image of self-assembled silver nanowires produced at the University of Chicago. Silver wires in this image are colored blue-grey. The different color shades correspond to different orientations of small crystallites that have flues to form the wires. Polymethylmethacrylate domains between the wires are not wetted by silver metal and appear pinkish. The center-to-center spacing between neighboring wires is 50 nanometers.

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. Image courtesy of Heinrich Jaeger and Ward Lopes
