Nanotechnology:  New tricks with nanotubes

M. S. Dresselhaus1

Carbon nanotubes are seamlessly rolled single sheets of carbon atoms, only a few nanometres across. Two papers in this issue, Wildöer et al.1 on page 59 and Odom et al.2 on page 62, present strong experimental evidence for the remarkable electronic properties that were predicted3 in 1992 — namely, that they can be either metallic or semiconducting depending on their diameter and helicity.
