Introduction to Nanotechnology
 Nanotechnology is the study and application of
extremely small things and can be used across
various fields

4.
A nanometer is…
 one billionth of a meter
How Small Is Nanometer?
Human Hair: Approx. 1x105 nm
DNA Sample: Approx. 2 nm

Origins of Nanotechnology
 Richard Feynman first conceived the idea of
molecular manufacturing in 1959
 Richard Feynman was the first scientist to
suggest that devices and materials could
someday be fabricated to atomic
specifications
 In 1986, K. Eric Drexler introduced the term
nanotechnology from there Scientific
research expanded to what we know today.

7.
Why Nanotechnology?
 At the nanoscale, the physical, chemical,
and biological properties of materials differ
in fundamental and valuable ways from
the properties of individual atoms and
molecules or bulk matter.
 Nanotechnology research and
development is directed towards
understanding and creating improved
materials, devices, and systems.

16.
Disadvantages Of
Nanotechnology
1. Loss of jobs (manufacturing, farming, etc)
2. Oil Becomes worthless
3. increased production of DNA damage, genotoxic
effects, damages to organs and tissues in
humans.
4. effects on growth and yield of crop plants.
5. Atomic weapons more accessible and

17.
Future of Nanotechnology
 Nanotechnology will redesign the future of
several technologies, products and
markets.
 Scientists and engineers can now work
with materials at the atomic level to create
stain-proof fabrics, scratch-resistant
paints, more efficient fuel cells and
batteries

18.
Conclusion
 Nanotechnology offers the ability to build
large numbers of products that are
incredibly powerful
 Nanotechnology is heavily intertwined with
biotechnology and information technology,
making its scope very wide
 The nanotechnology industry is mainly
used to create a better advanced world
