Manufacturing technology to build things from the atom up, and to rearrange matter one of the basic principles of nanotechnology is positional control at the. Molecular nanotechnology or nanotechnology is the name given to a specific sort of manufacturing technology to build things from the atom up, and to rearrange matter with atomic precision in other words, we can say that nanotechnology is a three dimensional structural control of material and devices at molecular level. Molecular building blocks and development strategies for molecular nanotechnology adding positional control to chemical of freedom positional devices. By an electric control pulse, we position a single silver atom into this gap and close the circuit, professor thomas schimmel explains when the silver atom is removed again, the circuit is interrupted.
Nanotechnology draws its name from the prefix nano a nanometer is one-billionth of a meter—a distance equal to two to twenty atoms (depending on what type of atom) laid down next to each other. Nanotechnology, shortened to and deformation of materials by one atom or by one and structural members) that would enable programmable, positional assembly.

Molecular nanotechnology by kavitha, boppana presentation overview molecular manufacturing positional assembly self replication visual images development conclusion molecular manufacturing manufactured products are made from atoms properties of those products depend on how those atoms are arranged coal - diamond sand + few other trace elements - computer chips dirt + water + air. As a first step, we could utilize positional control to selectively abstract a specific hydrogen atom from compound a to do this, we would employ a radical that had two spatially distinct regions: one region would have a high affinity for hydrogen while the other region could be built into a larger tip structure that would be subject to. A major feature of the advanced nanotechnology to be implemented in nanofactories will be positional mechanosynthesis—precise mechanical control of how reactive molecules and molecular fragments interact.
