Nanoid
A Nanoid
'Nanotechnology' refers to meterials and working devices that are engineered at the scale of atoms and molecules. In the metric system 'nano' refers to one billionth, so 1 nanometre (nm) is a billionth of a metre.
To help put this into real terms, consider that 1nm is roughly the width of 1/50,000th of a human hair. A DNA strand is 2nm wide, and a single red blood cell is 2,500nm wide.
Nano materials are special because they are able to utilise unusual properties (electrical, optical and others), which are determined by the particular arrangement of the atoms. Properties can include super strength, water or fire resistance and electrical conductivity.
