Electronics on a nanometer scale, whether made by current techniques or nanotechnology; includes both molecular electronics and nanoscale devices resembling today's semiconductor devices.

Design and analysis of systems that are theoretically possible but cannot be built yet, owing to limitations in available tools.

A variety of pharmaceutical techniques and therapies in use today.

A general-purpose device for molecular manufacturing capable of guiding chemical reactions by positioning molecules.

The smallest unit of a chemical element, about a third of a nanometer in diameter. Atoms make up molecules and solid objects.

An instrument able to image surfaces to molecular accuracy by mechanically probing their surface contours. A kind of proximal probe.

Engineering design done by a computer system, generating detailed designs from broad specifications with little or no human help.

As used here, nanotechnology-based manufacturing requiring little human labor.

Single-celled microorganisms, about one micrometer (one thousand nanometers) across.

Technology in which atoms and molecular are manipulated in bulk, rather than individually.
