This document discusses nanotechnology. It begins with a list of names and then poses several questions about nanotechnology, including what it is, when it was invented, why it is called "nano", where it is used, and how it will build our future. It then provides answers to these questions, explaining that nanotechnology works at the nano scale and was first conceptualized by Richard Feynman in 1959. It provides examples of medical applications like using nano robots to detect and destroy cancer cells without harming healthy cells. It also discusses uses of nanotechnology in materials, fabrics, energy production and efficiency, and that while it is currently used passively in products like cosmetics, research is being done on artificial body parts

 When is it invented?
 Why “nano”?
 Where used?
 How it builds our future?

5.  Nanotechnology is a science where
everything works in nano scale .
 The first use of the concepts in 'nano-
technology' (but predating use of that
name) was in "There's Plenty of Room at
the Bottom," a talk given by physicist
Richard Feynman at an American Physical
Society meeting at Caltech on December 29,
1959.
 Why NANO !? It is better to question why
not NANO ?

8.  Inject nano robots into the
patient
 Detect cancer cell
 Destroy cell
 Do not effect on healthy
cell

9.  New research published
in Advanced Functional
Materials provides some of the
groundwork necessary to one
day develop mini-robots that
could perform delicate tasks
inside our body. As the thinking
goes, these nanotechnologies
would be able to swim in our
bloodstream and even assemble
medical devices inside our
body.

10.  The basic concept of
pollution control on a
molecular level is
separating specific elements
and molecules from a
mixture of atoms and
molecules . The current
method for separating
atoms is thermal
partitioning, which uses
heat to force phase changes

11. Making composite fabric with nano-sized particles
or fibers allows improvement of fabric properties
without a significant increase in weight, thickness,
or stiffness as might have been the case with
previously-used techniques

12. Nanowhiskers that cause water to bead up, making the
fabric water and stain resistant.
Silver nanoparticles in fabric that kills bacteria making
clothing odor- resistant.
Nanopores providing superior insulation for shoe
inserts in cold weather.
Nanoparticles that provide a "lotus plant" effect for
fabric used awnings and other material left out in the
weather, causing dirt to rinse off in the rain.

13. Company Product Advantage
Nano-tex Fabric enhanced with
nanowhiskers Water and stain resistant
Aspen
Aerogel
Fabric enhanced with nanopores Insulates against heat or chill
BASF Fabric enhanced with
nanoparticles (Mincor® TX TT)
Dirt rinses off in rain, similar to
property of the lotus plant
Nano
Horizons
Fabric enhanced with silver
nanoparticles Reduces odors

14. Nanotechnologies provide the potential to
enhance energy efficiency across all brunches of
energy industry and to economically leverage
renewable energy production through new
technological solutions and optimized production
technologies.

15. Nanotechnologies provide essential improvement
potentials for the development of both
conventional energy source (fossil and nuclear)
and the renewable energy sources like geothermal
energy, sun, wind, water, tides or biomass

16. Nanotechnology involves manipulating properties
and structure at nanoscale often involving
dimensions that are just tiny fractions of the width
of a human hair.
Nanotechnology is already being used in products
in its passive form, such as cosmetics and
sunscreens.
