The CNT-DNA wrap: A hefty hybrid for carbon nanotubes

Since their discovery in 1991, carbon nanotubes (CNTs) have captured the public imagination. These scrolls of graphite are much too tiny to be seen but they are stronger than diamonds. Formed from organic material, they can be shaped in a variety of ways and can act as metals or as semiconductors. They offer great potential in nanoelectronics, medicine, sensing and lasers, and as strengthening elements in composite materials.
