Nanotechnology explained: Nanowires and nanotubes

April 12, 2013

Nanowires and nanotubes, slender structures that are only a few billionths of a meter in diameter but many thousands or millions of times longer, have become hot materials in recent years. They exist in many forms — made of metals, semiconductors, insulators and organic compounds — and are being studied for use in electronics, energy conversion, optics and chemical sensing, among other fields.
