  Mechanosynthesis -- Facts, Info, and Encyclopedia article   (Site not responding. Last check: 2007-10-08)
In mechanosynthesis, reactive ((physics and chemistry) the simplest structural unit of an element or compound) molecules are attached to molecular mechanical systems, and their encounters result from mechanical motions bringing them together in planned sequences, positions, and orientations.
Mechanosynthesis can avoid unwanted reactions by keeping potential reactants apart, and can strongly favor desired reactions by holding reactants together in optimal orientations for many molecular (The act of vibrating) vibration times.
Eric Drexler, that mechanosynthesis will be fundamental to (additional info and facts about molecular manufacturing) molecular manufacturing based on (additional info and facts about nanofactories) nanofactories capable of building macroscopic objects with atomic precision.

Mechanical engineers are also expected to understand and be able to apply concepts from the chemistry and electrical engineering fields.
At the smallest scales, mechanical engineering becomes molecular engineering - one speculative goal of which is to create a molecular assembler to build molecules and materials via mechanosynthesis.
For now this goal remains within exploratory engineering, and some consider it science fiction.
