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.
What I want: a very powerful miniature home medical test lab. Get your blood, and assorted secretions tested any time you want. Very early stage cancer testing in your own bathroom would be especially good. Catch and remove the cancer before it spreads. But very early stage means very small. The hard part will be to precisely locate it once it leaves some sort of signature in the blood.
