It is a long way from the slender nanotube—a chicken-wirelike cylinder of carbon a billionth of a meter thick—to a revolution in electronics. The very smallness that makes nanoscale materials so attractive as components of next-generation electronics also makes them extremely challenging to manipulate collectively. Investigators in the field hope, therefore, to realize commercial devices by piggybacking on existing manufacturing techniques. This year has seen several demonstrations of how nanoscale components might be integrated with conventional manufacturing as well as a report outlining a regulatory protocol for nanomaterials.
