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 nanomedicine and so on.Soon you
have trillions of assemblers controlled by nano super computers working in parallel
assembling objects quickly.
