NANOTECHNOLOGY
Let us first examine the principle question
What is Nano Technology?
It is a multidisciplinary science that looks at how we can manipulate matter at the molecular and atomic level. Atoms are still relatively smaller than a nanometer hence it is inevitably difficult to quantify an atom's size.
A general purpose technology
Nanotechnology is sometimes referred to as a general-purpose technology. That's because in its advanced form it will have significant impact on almost all industries and all areas of society. It will offer better built, longer lasting, cleaner, safer, and smarter products for the home, for communications, for medicine, for transportation, for agriculture, and for industry in general.
As we learn more about how molecules work and how to manipulate them, we can change the world. The biggest revelations will come from the smallest of sources.
The big idea
By manipulating molecules to form particular shapes, we can make all sorts of interesting materials. For instance, we can build materials with amazing properties. One example is a carbon nanotube. To create a carbon nanotube, you start with a sheet of graphite molecules, which you roll up into a tube. The orientation of the molecules determines the nanotube's properties. You could, for one, end up with a conductor or a semiconductor. Rolled the right way, the carbon nanotube will be hundreds of times stronger than steel but only one-sixth the weight!
"I want to build a billion tiny factories, models of each other, which are manufacturing simultaneously. . . The principles of physics, as far as I can see, do not speak against the possibility of maneuvering things atom by atom. It is not an attempt to violate any laws; it is something, in principle, that can be done; but in practice, it has not been done because we are too big."
— Richard Feynman, Nobel Prize winner in physics
