Nanotech is the Nanoscale of the Future : The Study, Control and Engineering of Matter at the Level of Atoms and Molecules is the Next Scientific Wave

What is nanotechnology?

The Wikipedia relates, for example, that:"DNA nanotechnology utilizes the specificity of Watson-Crick basepairing to construct well-defined structures out of DNA and other nucleic acids" and that the element "Gold" at the nanoscale of nanotech is liquid at room temperature.

Nanotechnology (Nanotech) is the coming scientific wave of the future, dealing with the study, control and engineering of matter at the nanoscale of atoms and molecules. As written at the Wikipedia article on Nanotechnology:

• Generally nanotechnology deals with structures of the size 100 nanometers or smaller, and involves developing materials or devices within that size....
  
  
• One nanometer (nm) is one billionth, or 10^-9, of a meter. By comparison, typical carbon-carbon bond lengths, or the spacing between these atoms in a molecule, are in the range 0.12-0.15 nm, and a DNA double-helix has a diameter around 2 nm. On the other hand, the smallest cellular life-forms, the bacteria of the genus Mycoplasma, are around 200 nm in length.
  
  
• To put that scale in another context, the comparative size of a nanometer to a meter is the same as that of a marble to the size of the earth.
  
  
• Or another way of putting it: a nanometer is the amount a man's beard grows in the time it takes him to raise the razor to his face.
