How to assemble nanostructures

There are two main approaches to the creation of structures in the nanometer scale: self-assembly and positional.

When positional assembly of researchers using any device, like a miniature robotic arm or other microscopic tools for assembling molecules one by one manually.
On the other hand, is much less laborious self, because it uses the natural tendency of certain molecules to find each other. For samosobirayuschihsya components, all that is required of the person - it is enough to put them in the tube and allow them to automatically come to the right konfiruratsii according to their natural properties.

Construction of a complex system requires nanorobotnoy production technology in which the molecular structures arranged with the help of a computer model of diamond mechanosynthesis (DMS). DMS - this is controlled addition of carbon atoms on the surface of the diamond lattice in a vacuum. Covalent chemical bonds are formed sequentially as the result of positionally attached mechanical effort in a programmed sequence.
