Introduction to Nanotechnology

Definition of Nanotechnology
“Nanotechnology is the understanding and control of matter at
dimensions of roughly 1 to 100 nanometers, where unique phenomena
enable novel applications.
Encompassing nanoscale science, engineering and technology,
nanotechnology involves imaging, measuring, modeling, and manipulating
matter at this length scale.”
-National Nanotechnology Initiative

What is Nanometer?
“The nanometre (International spelling as used by the International
Bureau of Weights and Measures; SI symbol: nm) or nanometer (American
spelling) is a unit of length in the metric system, equal to one billionth of
a metre. The nanometre is often used to express dimensions on an atomic
scale
The name combines the SI prefix nano- (from the Ancient Greek ?????,
nanos, "dwarf") with the parent unit name metre (from Greek ??????,
metr?n, "unit of measurement"). It can be written in scientific notation as
1×10?9 m, in engineering notation as 1 E?9 m, and is simply
1/1,000,000,000 m. One nanometre equals ten angstroms.
