Nanotechnology involves manipulating materials at the nanoscale of 1 to 100 nanometers. While nanomaterials have been unintentionally produced for decades, the ideas and modern field of nanotechnology began in 1959 with Richard Feynman's talk and the term was coined in the 1970s. Today, nanotechnology is being applied in various fields like medicine, food, fuel cells, electronics, solar cells, space, and textiles. Potential risks include inhalation exposure and environmental impacts, so further research is still needed to develop applications safely.

2.  Nanotechnology is science, engineering, and
technology conducted at the Nano scale, which
is about 1 to 100 nanometers.
 nanotechnology is the measuring, design,
characterization, production, and application of
structures, devices, and systems by controlled
manipulation of size and shape at the
nanometer scale

4.  Materials in the nanometer range have been
produced for several decades. Carbon Black,
for example, has been used in tires since 1930.
 The ideas of Nano science started with a talk
“There’s Plenty of Room at the Bottom” by
Richard Phillips Feynman, (American
theoretical physicist) and says scientists would
be able to manipulate and control individual
atoms and molecules in December 29, 1959.

5.  And after a decade later, Professor Norio
Taniguchi coined the term nanotechnology. It
this tech wasn’t well developed until the
development of the scanning tunneling
microscope that could "see" individual atoms in
1981 after that modern nanotechnology began.

6.  Physicist Richard Feynman, the father of
nanotechnology.

7.  Nano materials have been produced for
several years. Today Nano particles can be
made by rearranging the atoms of materials we
can made new materials with new properties

8.  Medicine
These days scientists are developing nanoparticles
the size of that can deliver drugs directly to
diseased cells in our body they can repair cell, treat
wound, detect cancer with Diagnostic Technique.

10. Again, special types of
nanotubes help to wash
the accumulation in
blood vessels that is
preventing the normal
flow of blood.
 Blood flow in blood
vessels that have less
space to pass is
referred to what we
call hypertension

11.  Food
 With the help of Nano sensors that can detect
bacteria and other with the contaminates at a
packaging plant. This will allow for frequent
testing at a much lower cost than sending samples
to a lab for analysis. And reduce the chance of
contaminated food reaching grocery store shelves.
 And there are also developing Nano capsules
containing nutrients that would be released when
Nano sensors detect a vitamin deficiency in your
body. Basically this research could result in a super
vitamin storage system in your body that delivers
the nutrients you need, when you need them.

12.  Fuel Cells
 Fuel cells have membranes that allow hydrogen ions to
pass through but prevent other atoms or ions from
passing through, such as oxygen. Companies are
harnessing nanotechnology to develop more effective
membranes, allowing them to make fuel cells that are
lighter and last longer. Nano-Fuels Nano fuels are
made up of nanoparticles plus a base fuel (such as
diesel, biodiesel, or fuel mixes). These nanoparticles
work as hybrid Nano catalysts with a lot of reactive
surface area. The Nano-ultrasonic additive's dispersion
increases fuel performance significantly, including
reduced ignition delay, longer flame sustain, and
agglomeration ignition, as well as considerable overall
emission reductions.

14.  Electronics
 Flexible electronic circuits. Researchers are
aiming for a combination of flexibility, a simple
fabrication process and low power
requirements.
 Modern microprocessor built from
complementary carbon nanotube transistors

15.  Solar Cells
It commonly uses Nano-sized particles. These
solar panels are extremely flexible and are
sometimes even transparent due to the use of zinc-
oxide nanoparticles. Scientists are currently further
researching and developing this technology.

16.  Space
 Employing materials made from carbon
nanotubes to reduce the weight of spaceships
while increasing the structural strength. And
Using carbon nanotubes to make the cable
needed for the space elevator, a system which
could significantly reduce the cost of sending
material into orbit

18. Specialized Fabrics
 Nanomaterials in textiles have proved to be
immensely valuable for the manufacturing of
protective garments for workers involved in
emergency services such as military personnel,
firefighters and medical workers.

19.  Medical Uses:
- Measure Heart rate, body
temperature, and breathing pattern
are all monitored using Nano-
engineered textiles.

20.  Military Uses:

21. -Fabrics that are lightweight but have
excellent resistance to extreme
temperatures
-Durable
-Have antibacterial activity
-Water-resistant
-Embedded with multipurpose
nanosensors.
-The textiles are also highly anti-ballistic,
flame-resistant, and RF-shielding. These
qualities are perfect for military use.

22.  Inhalation exposure
 Danger of ending up in aquatic ecosystems
 Affect the proper relationship between man
and nature
