Toward ultra-portable electronic devices

Scientists are reporting a key advance toward the long-awaited era of “single-molecule electronics,” when common electronic circuits in computers, smart phones, audio players, and other devices may shrink to the size of a grain of sand.

The breakthrough is a method for creating and attaching the tiny wires that will connect molecular components, reports a new study in the Journal of the American Chemical Society.

The wiring method can be used to connect molecular switches, memory bits, and transistors. The scientists say their technique “will enable us to develop cheaper, higher-performance, and more ecological alternatives to conventional silicon-based devices.”
