Nanotechnology: Definition
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.
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”)
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.
