Diamondoid Molecular Machine Parts


In Nanosystems, Dr. K. Eric Drexler describes a range of molecular machines based on stiff, easily-modeled covalent structures. Construction of such machines will require programmable molecular assemblers (or special-purpose molecular mills) able to position reactive molecules with atomic precision, guiding chemical reactions to build up complex structures. Thus, such machines are beyond the reach of today’s laboratory synthesis capabilities, though within reach of today’s computational modeling techniques.

Several devices, such as bearings and gears composed of several thousand atoms, have been specified in atomic detail. Proposals for larger devices, such as sorting rotors and robotic arms, are (like macroscopic machine systems) described at lower resolution.

Some atomically detailed designs include:

Ralph Merkle has assembled a page of high resolution images of proposed molecular devices.

New designs using NanoEngineer are available in the NanoRex galleries.
