Nanotechnology. Although not to be found in any Webster's Dictionary, it is concemed with the world of invisible miniscule particles that are dominated by forces of physics and chemistry that cannot be applied at the macro- or human- scale level. These particles have come to be defined by some as nanomaterials, and these materials possess unusual properties not present in traditional and or ordinary materials.
Regarding the word nanotechnology, it is derived from the words nano and technology. Nano, typically employed as a prefix, is defined as one-billionth of a quantity or term that is represented mathematically as 1 x 10-9, or simply as 10-9. Technology generally refers to "the system by which a society provides its members with those things needed or desired." The term nanotechnology has come to be defined as those systems or processes that provide goods and or services that are obtained from matter at the nanometer level, that is, from gizes in the range of one-billionth of a meter. The new technology thus allows lhe engineering of matter by systems and or processes that deal with atoms; or as Drexler (who some view as lhe godfather of this industry) put it: "... entails the ability to build molecular systems with atom-by-atom precisions, yielding a variety of nanomachines". ane of lhe major problems that remain is the develop- ment of nanomachines that can produce other nanomachines in a manner similar to what many routinely describe as mass production.
