Stamping out low cost nanodevices
Date:5/31/2011

A simple technique for stamping patterns invisible to the human eye onto a special class of nanomaterials provides a new, cost-effective way to produce novel devices in areas ranging from drug delivery to solar cells.

The technique was developed by Vanderbilt University engineers and described in the cover article of the May issue of the journal Nano Letters.

The new method works with materials that are riddled with tiny voids that give them unique optical, electrical, chemical and mechanical properties. Imagine a stiff, sponge-like material filled with holes that are too small to see without a special microscope.

For a number of years, scientists have been investigating the use of these materials called porous nanomaterials for a wide range of applications including drug delivery, chemical and biological sensors, solar cells and battery electrodes. There are nanoporous forms of gold, silicon, alumina, and titanium oxide, among others.

Simple stamping

A major obstacle to using the materials has been the complexity and expense of the processing required to make them into devices.

Now, Associate Professor of Electrical Engineering Sharon M. Weiss and her colleagues have developed a rapid, low-cost imprinting process that can stamp out a variety of nanodevices from these intriguing materials.

"It's amazing how easy it is. We made our first imprint using a regular tabletop vise," Weiss said. "And the resolution is surprisingly good."

The traditional strategies used for making devices out of nanoporous materials are based on the process used to make computer chips. This must be done in a special clean room and involves painting the surface with a special material called a resist, exposing it to ultraviolet light or scanning the surface with an electron beam to create the desired pattern and then applying a series of chemical treatments to either engrave the surface or lay down new
