Researchers from the University of Minnesota and Seoul National University have developed a new lithographic method with the help of a very low-tech tool: Scotch Magic tape. This new method, which promises to enhance our ability to fabricate nanostructures, has been used to build highly nonlinear optical materials consisting of sheets of 25 micron (0.001 in) metal blocks separated by nanometer-wide insulating channels. As light squeezes through these channels, incompletely understood plasmonic effects enable novel optical behavior.
