Abstract:
A nanometer is one billionth of a meter. If you blew up a baseball to the size of the earth, the atoms would become visible, about the size of grapes. Some 3- 4 atoms fit lined up inside a nanometer. Nanotechnology is about building things atom by atom, molecule by molecule. The trick is to be able to manipulate atoms individually, and place them where you wish on a structure.
Nanotechnology uses well known physical properties of atoms and molecules to make novel devices with extraordinary properties. The anticipated pay off for mastering this technology is beyond any human accomplishment thus far.
Nature uses molecular machines to create life.Scientists from several fields including chemistry, biology, physics, and electronics are driving towards the precise manipulation of matter on the atomic scale. How do we get to nanotechnology? Several approaches seem feasible. Ultimately a combination may be the key.
The goal of early nanotechnology is to produce the first nano-sized robot arm capable of manipulating atoms and molecules into a useful product or copies of itself. Nanotechnology finds applications as nanotubes, in nano medicine and so on.Soon you have trillions of assemblers controlled by nano super computers working in parallel assembling objects quickly.
Ultimately, with atomic precision, everything could be made. Itâ„¢s all a matter of software.
