RogerRoast writes "Vanderbilt University scientists report that they have developed a simple technique for stamping patterns invisible to the human eye onto a special class of nanomaterials. According to the article, the method works with materials that are riddled with tiny voids that give them unique optical, electrical, chemical and mechanical properties. 'It's amazing how easy it is. We made our first imprint using a regular tabletop vise,' Sharon M. Weiss the lead author said. The article was published in the latest issue of the journal Nano Letters."
