Molecular engineering

Molecular engineering is any means of manufacturing molecules. It may be used to create, on an extremely small scale, most typically one at a time, new molecules which may not exist in nature, or be stable beyond a very narrow range of conditions.

Today this is an arduous process, requiring manual manipulation of molecules using such devices as a scanning tunneling microscope. Eventually it is expected to exploit life-like self-replicating 'helper molecules' that are themselves engineered. Thus the field can be seen as a precision form of chemical engineering that includes protein engineering, the creation of protein molecules, a process that occurs naturally in biochemistry, e.g., prion reproduction. However, it provides far more control than genetic modification of an existing genome, which must rely strictly on existing biochemistry to express genes as proteins, and has little power to produce any non-proteins.

Molecular engineering is an important part of pharmaceutical research and materials science.

Molecular engineering of hydrocarbon fuels and many pharmaceuticals are carried out through a process known as "PLASMA CATALYSIS" with the help of the invention" HYDRODRIVE ELECTRONIC CATALYTIC CONVERTER".More details:

Emergence of scanning tunneling microscopes and picosecond-burst lasers in the 1990s, plus discovery of new carbon nanotube applications to motivate mass production of these custom molecules, drove the field forward to commercial reality in the 2000s.

As it matures, it is seeming to converge with mechanical engineering, since the molecules being designed often resemble small machines. A general theory of molecular mechanosynthesis to parallel that of photosynthesis and chemosynthesis (both used by living things) is the ultimate goal of the field. This may lead to a molecular assembler, according to some, such as K. Eric Drexler, Ralph Merkle, and Robert Freitas.

Molecular engineering is sometimes called generically "nanotechnology", in reference to the nanometre scale at which its basic processes must operate. That term is considered to be vague, however, due to misappropriation of the word in association with other techniques, such as X-ray lithography, that are not used to create new free-floating ions or molecules.

Future developments in molecular engineering hold out the promise of great benefits, as well as great risks. See the nanotechnology article for an extensive discussion of the more speculative aspects of the technology. Of these, the one that sparks the most controversy is that of the molecular assembler.
