1.INTRODUCTION
The purpose of this paper is to know what is nanotechnology, what are its advantges and
disadvantages, so first of all nanotechnology is the study and application of extremely small
things and can be used across all the opposite science fields, like chemistry, biology, physics,
materials science, and engineering conducted at the nanoscale. A nanometre is one-
billionth of a metre, to have an idea how small is nanometre I will give you an example, let’s
take a look to the back of your hand. Using just your eyes you can focus down to a scale of 1
centimeter to 1 millimeter. At this scale the skin looks flat, so get out a glass and now you
can see it’s actually cracks and folds. The glass can help you to study the fine structure of
the skin at less than a millimetre (or one thousand of a metre).
If you look closely with a microscope, you could see the cells that are making up your skin,
now you’re looking at the scale of micrometres, cells and bacterias are measured in
micrometres, but this isn’t enough we have to go smaller, which is a nanometre, the scale at
which we measure atoms and molecules they make. A human hair is between 50,000 and
100,000 nanometres thick.
Nanotechnology involves the flexibility to ascertain and to manage individual atoms and
molecules. Everything on Earth is formed from atoms, so we can find atoms in the food we
eat, in the garments we wear, in the buildings and houses we sleep in, and in our own
bodies.
In conclusion, nanotechnology offers the potential for new and faster kinds of computers,
more efficient power sources and life-saving medical treatments. Potential disadvantages
include economic disruption and possible threats to security, privacy, health and the
environment.
2.APPLICATIONS AND USES
Nanotechnology can be applied in all varieties of industrial sectors,
It can be found in these areas:
Electronics
Nanotechnology has greatly contributed to many advances in computing and electronics, an
example is to improving display screen or increasing the density of memory chips.
Energy
Many scientists are looking into ways to develop clean, affordable, and renewable energy
sources, like within the Kyoto University, they're making their possible to manufacture solar
panels that double the quantity of sunlight converted into electricity.
