3. Introduction: Nanotechnology
Nanotechnology is the understanding and control of matter at dimensions between
approximately 1 and 100 nanometers (nm), where unique phenomena enable novel
applications not feasible when working with bulk materials or even with single atoms
or molecules.
A nanometer is one-billionth of a meter. A sheet of paper is about 100,000 nanometers
thick; a single gold atom is about a third of a nanometer in diameter.
Researchers seeking to understand the fundamentals of properties at the nanoscale call
their work nanoscience; those focused on effective use of the properties call their
work nanoengineering.
Encompassing nanoscale science, engineering, and technology, nanotechnology
involves imaging, measuring, modeling, and manipulating matter at the nanoscale.

4. What is Nanoscale?
The nanoscale is the dimensional
range of approximately 1 to 100
nanometers.
A nanometer is one billionth of a
meter. (A meter is 39.37 inches, or
slightly longer than one yard.) The
prefix “nano” means “one
billionth”)

5. Atoms are the building blocks for all matter in our natural world. An atom is made up of a small,
heavy nucleus in the centre surrounded by a relatively large, light cloud of electrons.
The nucleus consists of protons and neutrons that are made up of quarks. Atoms bonding together
form molecular structures. The molecule is the smallest indivisible portion of a pure compound that
retains a set of unique chemical and physical properties.
Molecules make up the air we breathe, the water we drink, even the living cells in our bodies -
nature's own nanomachines.
The goal of nanotechnology is to be able to manipulate each individual atom or molecule and
engineer them in a pattern to produce a desired structure - similar to arranging LEGO
®
bricks.
