Topic :
Nanoscience and its impacts on people’s
Development in the future

4. Do you know how it started ?
Richard Feynman
 The ideas and concept behind nanoscience and nano
technology started with a talk entitled ;
“THERE’S PLENTY OF
ROOM AT THE BOTTOM”
By physicist Richard feynman at an american physical society
meeting at the California institute of technology ( caltech) on
29, december, 1959, long before the term nano technology was
used.
Feynman described a process in which scientist would be able to
manipulate and control individual atoms and molecule.
(11 May, 1918 – 15 Feb, 1988)

6. What is nanoparticle ?
 Nanoparticle is any material having atleast one of its dimensions
in the range of 1-100 nm.
 “nano”- derived from a greek word “nanos” meaning DWARF or
small.
 “Nario tahiguchi”, 1974 – coined the term nanotechnology.
 A Nanometer is one billion on of a meter ( m)10-9

7. Comparison of Macro,Micro,and Nanoscale

8. Nano - simple example
The population of India is one billion or 100 crores. Each Indian – you or
me is nano in comparison with the total population of India

9. Nano - simple example
• One rupee in 100 crore rupees.
• One rupee note

10. Why small is good ?
Faster
Lighter
Can get into small spaces
Cheaper
More energy efficient
Different properties at very
small scale.
NANO- OBJECTS are :-
Surface area increases as size decreases

11. How do nanomaterials change our lives?

12. CARBON NANOTUBES
Carbon nanotubes (CNTs) are cylindrical molecules that consist of rolled-up sheets of
single-layer
carbon atoms (graphene). They can be single-walled (SWCNT) with a diameter of less
than 1 nanometer (nm) or multi-walled (MWCNT), consisting of several concentrically
interlinked nanotubes, with diameters reaching more than 100 nm. Their length can
reach several micrometers or even millimeters.
Like their building block graphene, CNTs are chemically bonded with sp2 bonds, an
extremely strong form of molecular interaction. This feature combined with carbon
nanotubes’ natural inclination to rope together via van der Waals forces, provide the
opportunity to develop ultra-high strength, low-weight materials that possess highly
conductive electrical and thermal properties. This makes them highly attractive for
numerous applications.
Apart from their electrical properties, which they inherit from graphene, CNTs also have
unique
thermal and mechanical properties that make them intriguing for the development of
new materials:
•their mechanical tensile strength can be 400 times that of steel;
•they are very light-weight – their density is one sixth of that of steel;
•their thermal conductivity is better than that of diamond;
•they have a very high aspect ratio greater than 1000, i.e. in relation to their length they are extremely
thin;
•a tip-surface area near the theoretical limit (the smaller the tip-surface area, the more concentrated
the electric field, and the greater the field enhancement factor);

13. NANOTECHNOLOGY IN SPORTS EQUIPMENT : THE GAME CHANGER
Tennis rackets, golf clubs, baseball and softballs bats- all made with high strength light
Weight plastic composites that contain carbon nanotubes.
The famous tennis player, Roger Federer has won many tournaments including
Wimbledon using nano-enhanced racquets. In Formula One Motor racing,
where race largely depends on the motor body-weight and type of tyres,
lighter-weight and better-wearing nanocomposite products are being seized
upon.
Impact of Nanotechnology on Sporting Equipments : The degree of competitiveness in sports has
been remarkably impacted by nanotechnology like any other innovative idea in materials science. Within the niche
of sport equipments, nanotechnology offers a number of advantages (Fig. 1)

14. NANOTECHNOLOGY IN MEDICINE ( NANOMEDICINE )
Nanotechnology has potential to remarkably affect the diagnostic and therapeutic approach for a disease. The unparallel sensitivity and
performance, enhanced durability and flexibility, unique physicchemical properties of nano-materials, have been exploited in medical
diagnosis (Table 1) for early detection of diseases, in target approached clinical therapy (Table 2) and in regenerative medicine for
reconstruction of damaged tissues.

Drugs might be used to treat cancer.

16. FUTURE CASE STUDY
Bone crack filling nanobots

17. NANOBOTS AND ITS APPLICATION
More specifically, nanorobotics refers to the
still largely theoretical nanotechnology
engineering discipline of designing and
building nanorobots.
Nanorobots (nanobots or nanoids) are typically
devices ranging in size from 0.1-10
micrometres and constructed of nanoscale or
molecular components.
As no artificial non-biological nanorobots have
so far been created, they remain a
hypothetical concept at this time.

18. FUTURE CASE STUDY
Humanity has always created new
technologies and each technology has had its
risks. Anyone can make a small nanobots ( size
comparably to a housefly ) which can inject
poison to any person or may be the president
of the country and kill the person. It seems
that the more advanced the technological
achievements of humanity become the greater
the inherent risks of the innovations. Yet,
through awareness, control, forethought, and
possibly luck humanity is still present in the
universe. We have not blown ourselves off the
surface of the planet. The very fact that
humanity is aware of the risks posed by the
fields of natural computation is the first step in
averting these risks and establishing guidelines
for research and use of these upcoming
technologies.

20. FUTURE CASE STUDY
Lizards have pad on their feet. These pads consist of wide plates or scales and are
present below their fingers and toes. The outer layer of each plates or scales is
composed of innumerable tiny hooks for med by free, bent tips of cells. These
minute hooks create the condition like as suction pump and thus enable lizards to
run up on apparently smooth Walls and even upside down on plaster ceilings.
Anyone can make a suit which also have scales on
its surface like as lizard which abler us to climb
on the building , towers, and huge sculptures,etc

nano particles of zinc, calcium other materials that kill bacteria.
3. IMPROVED FOOD STORAGE: Nano-enhanced barrier keeps oxygen-sensitive foods
fresher.
4. ENHANCED NUTRIENT DELIVERY

and other ‘nutraceuticals
5. GREEN PACKAGING: Nano-fibers made from lobster shells or organic corn are
both antimicrobial and biodegradable.
6. PESTICIDE REDUCTION: A cloth saturated with nano fibers slowly releases
pesticides, eliminating need for additional spraying and reducing chemical leakage
into the water supply.

22. FRAME WORK OF NANOTECH IN INDIA
Scope of Nanotechnology: India: India is still in the development stage for Nanotechnology and it will take
quite a few years for this field to become established in India. Research labs and institutions such as IISc, TIFR, NCBS,
IITs etc are performing excellent research in India. However, when compared with countries such as UK, Germany
and USA, output of high quality research pales significantly. This is due to several reasons such as lack of integration
between different departments for R&D in Nanotechnology. Students interested in the research aspect of
Nanotechnology can join any one of the prestigious institutions listed below. On the other hand, students interested
in working in the Nanotechnology industry have limited options.
Companies, Universities and Research Institutions in India for Nanotechnology:
Centre for Research in Nanotechnology & Science (CRNTS), IIT Bombay
Centre of Nanotechnology, IIT Roorkee
Bhabha Atomic Research Center, Mumbai
Institute of Nano Science and Technology (INST), Punjab
IBM Semiconductor Research and Development, Bangalore
Centre for Nanotechnology, IIT Guwahati
Centre for Nanotechnology and Nanoscience, Jamia Millia Islamia
Centre for Nanoscience and Nanotechnology, Bharathidasan University,
Tiruchirappalli
Apart from the above mentioned institutes, Nanotechnology research is also
conducted in the Physics, Chemistry, Materials Sciences and Biological Sciences
departments of famed institutions such as NCBS, IISc, TIFR, JNCASR, IITs and
NITs, IISERs, BITS Pilani, BARC, University of Hyderabad, CSIR etc.

23. CONCLUSION
Nanotechnology is predicted to be developed by the end of
21st century but much depends on our commitment to its
research.
Nanotechnology offers the ability to build large number of
products that are incredibly powerful by today’s standards.
The range of possible nanotechnology built products is
almost infinite.
Even if allowable products were restricted to a small subset
of possible designs,
 it would still allow an explosion of creativity and
functionality
Hence we the common people should be well known about
nanotecnology and make use of its outcome and let us
develop a new era on nanotecnology
