Understanding Nano Technology
Nano technology is the study of
manipulating matter on an atomic and molecular scale. It is a multidisciplinary
field that involves the study of physics, chemistry, biology, and engineering.
The prefix "nano" is derived from the Greek word "dwarf,"
and it represents one billionth of a meter.
Nanotechnology has been around for a
long time, but it was only in the past few decades that it has gained
significant attention. The concept was first introduced by Richard Feynman in
1959, and it has since grown into a vast field with numerous applications in
various industries.
The main goal of nanotechnology is
to create new materials and devices with unique properties and functions that
are not possible with conventional materials. Nanoparticles, for instance,
exhibit different properties than their bulk counterparts, such as increased
surface area, reactivity, and optical properties.
One of the main advantages of
nanotechnology is its ability to improve the efficiency and effectiveness of
existing technologies. For example, it has been used to develop better drug
delivery systems, more efficient solar cells, and more durable and lightweight
materials for aerospace applications.
Despite its promising potential,
nanotechnology also poses several challenges and risks. One of the main
concerns is the safety of nanoparticles, as they can potentially enter the body
and cause harm. Therefore, it is essential to conduct thorough research and
testing to ensure their safety before they are released into the market.
Overall, nanotechnology is a
fascinating field with numerous applications and potential benefits. As
research and development continue, it is expected to revolutionize various
industries and improve our daily lives.
Historical Development of Nano Technology
Nano technology is a relatively new
field of science that has developed over the last few decades. The concept of
nano technology can be traced back to the time of the Greeks and Democritus in
the 5th century B.C., when scientists considered the question of whether matter
is continuous, and thus infinitely divisible into smaller pieces, or composed
of small, indivisible and indestructible particles, which scientists now call
atoms.
In 1959, physicist Richard Feynman
gave a lecture at the California Institute of Technology in which he described
the possibility of manipulating and controlling individual atoms and molecules.
This lecture is often credited with laying the foundation for the development
of modern nano technology.
In the 1980s, the invention of the
scanning tunneling microscope (STM) allowed scientists to see individual atoms
for the first time. This breakthrough led to the development of the atomic
force microscope (AFM), which allowed scientists to manipulate individual atoms
and molecules.
The term "nano technology"
was first used by Japanese scientist Norio Taniguchi in a 1974 paper on
production technology that creates objects and features on the order of a
nanometer. Taniguchi advocated that nano technology consisted of the
processing, separation, consolidation, and deformation of materials by one atom
or one molecule.
In the 1990s, the field of nano
technology began to expand rapidly, with the development of new tools and
techniques for manipulating and studying individual atoms and molecules. Today,
nano technology has a wide range of applications in fields such as medicine,
electronics, and energy, and is considered to be one of the most promising
areas of scientific research.

The term nanoscale refers to the length scale at which nanotechnology
operates, typically between 1 and 100 nanometers. At this scale, materials and
structures exhibit unique properties and behaviors that differ from those at
larger length scales.
Nanoscale phenomena include quantum confinement effects, surface plasmon
resonance, and enhanced reactivity. These phenomena have been exploited in a
wide range of applications, including drug delivery, catalysis, and energy
storage.
Overall, the fundamentals of nanotechnology involve the study and
