1) Nanotechnology involves manipulating matter at the atomic or molecular scale, between 1 to 100 nanometers. It allows developing materials and devices with novel properties. 2) The field emerged in the 1950s from the work of scientists like Richard Feynman, who proposed manipulating atoms and molecules. The scanning tunneling microscope in the 1980s allowed seeing individual atoms, advancing the field. 3) Nanotechnology approaches include top-down methods that create nanostructures from larger materials using lithography or etching. Bottom-up methods assemble structures from atoms or molecules using techniques like self-assembly.

4. History
- The term "nanotechnology" was coined by the Japanese physicist Norio
Taniguchi in 1974.
- The field of nanotechnology emerged from the work of several scientists
in the 1950s and 1960s, including Richard Feynman.
- Feynman gave a seminal lecture in 1959 titled "There's Plenty of Room at
the Bottom" in which he discussed the possibility of manipulating and
controlling individual atoms and molecules, thus laying the foundation
for the field of nanotechnology.
- Feynman's ideas inspired other scientists to explore the possibilities of
manipulating matter on a nanoscale, leading to the development of the
field of nanotechnology.
- Feynman was a pioneering thinker who encouraged scientists to think
creatively and take risks, and his legacy continues to inspire researchers
in the field of nanotechnology today.
- In the 1980s, the development of the scanning tunneling microscope
made it possible to see and manipulate individual atoms and molecules,
further advancing the field of nanotechnology.

discovered BY Micheal Faraday over 150 years ago.
2)1959 Richard Feynman report a new field of physics. He subjected
atomic level of matter are possible to study.
3)1981 STM(scanning tunneling microscope) is invented by Gerd
Binning and Heinrich Rohrer, allowing researches to see individual
atoms and molecules for the first time.
4)The word nanotechnology was discover by prof ‘Nario Taniguchi’
coined .
5)The Japan was the first country in which International
Nanotechnology was held in the year of 1999, by the years
researcher create the first nanocars tiny vehicles made of

Materials used
One of the materials in nanotechnology that has been the
subject of the greatest research is carbon nanotubes.
Another common substance used in nanotechnology is
quantum dots.
Nanotechnology uses for nanoparticles include medication
delivery, catalysis, and environmental cleanupNanowires,
nanofibers, and nanocellulose are further materials utilised
in nanotechnology.
Nanofibers are used extensively in filtration, medication
delivery, and tissue engineering.
Nanocellulose is beneficial in many applications, including
paper and packaging, coatings, and biomedical
applications, thanks to its distinctive mechanical, thermal,
and optical properties.

8. · Nano-engineered materials make superior household
products such as degreasers and stain removers.
· Transistors, the basic switches that enable all
modern computing, have gotten smaller and smaller
through nanotechnology.
· Using magnetic random access memory (MRAM),
computers will be able to “boot” almost instantly.
· Nanotechnology could help meet the need for
affordable, clean drinking water through rapid, low-
cost detection and treatment of impurities in water.

12. Nanotech in India
Research and work on nanotechnology in India started in 2001 with
the formation of the NanoScience and Technology Initiative with
initial funding of Rs. 60 crores. In 2007, the GOI launched a 5-year
program called Nano Mission, it was allocated a budget of Rs 1,000
crores. It had a wider scope of objectives and much larger funding.
Fields involved in the mission were: basic research in
nanotechnology, infrastructure development, human resources
development, and global collaboration.
Results
India has published over 23,000 papers in nanoscience.
India ranked 3rd in papers published in 2018 behind only the USA and China.
There have been many patent applications in this field.
Concerns
Only 0.2% of the patents filed in the US Patent Office are from India in this field.
There are very few students who take up this field.
The target number of PhDs in nanotechnology is 10000 per year by the Ministry of HRD.
The contribution of the private sector is minimal in this domain. Even though there is a
lot of potential, the private sector is yet to show tremendous enthusiasm.
Scope for potential:
1. A team from IIT Madras used nanotechnology to decontaminate arsenic from
water.
2. A team from IIT Delhi has engineered a self-cleaning technology to be used in
the textile industry.

Possibilities of nanotechnology for
future :-
1. Nanotechnology for health purposes:-
Wearable fitness technology means we can monitor our health by strapping gadgets to
ourselves .There are even prototype electronic tattoos that can sense our vital signs..
2. Sensors,sensors,everywhere :-
The sensors rely on newly-invented nanotechnologies and manufacturing techniques to
make them smaller , more complex and more efficient .
3. Self healing structures :-
If cracks do appear then nanotechnology could play further role . Changing the structure
of materials at nanoscale can give them some amazing properties - by giving them a
texture that repels water.
4. Making big data possible:-
Nanotechnology is helping to create ultra - dense memory that will allow us to store
wealth of data . Nature has several example of big data processes efficiently being
performed in real time by tiny structures, such as part of the eye and ear that turns
external information for the brain.
5. Tackling climate change :-
The fights against climate change means we need naw ways to generate and use
electricity , and nanotechnology is already playing a role

14. Conclusion
Nanotechnology has the potential to revolutionize our lives presents almost
unlimited potential to make remarkable changes in virtually all fields ranging
from medicine, computer technology, construction, environmental remediation,
food industry, to new energy sources.
Despite presenting many potential benefits in many areas, nanotechnology of
today is still in its infancy as just a few projects have been commercialized. Many
are yet to undergo full lifecycle assessment.
The number of nanotechnology innovations continues to rise.
