Nanomachines - the Overview and Future Development of Nanomachines

...

“It will be a marvelous challenge to see if we can outdesign evolution. It would be a staggering accomplishment to mimic the simplest living cell (Whitesides, 2001).” There are several possible applications of nanomachines. In research field, they can scan the body or organic molecule in nano-scope, helping us learn its structure and function. In medical field, they can change the problematic DNA sequences, or produce correct DNA sequences to human body, and they can kill the cancer cell with the substitution of healthy cell. More general, all kinds of matter in real world is made by molecule, so if the control of nanomachines is possible, we can even build diamond, turn grass into bread, and build nano-scale computer. “In the next century, as the components of computers continue to shrink smaller and smaller, down to the molecular scale, their physical representation will become more and more like that of present-day computer data. It is explained in some detail how this ongoing process of miniaturization is likely to lead to a technology in which matter will acquire desirable physical and economic properties much like those of software. It will be possible to "read" and to "write" functioning computer components and logic structures at will; they will be manufactured locally, on demand, in a manner similar to the way we now "download" software onto disk drives. As we gain the capability to manipulate matter in more comprehensive and more sensitive ways on even finer scales, it would not be strange if matter itself were to become more like software. (Ellenbogen, 1997).”

In conclusion, although nanomachines are relative new compare to other technology, and accompany with some severe drawback, this technology has unprecedented positive outcomes and possibility to overcome the drawback, which led people to innovate and change the world.
