This document provides an overview of nanotechnology including its definition, tools used, market products, and potential concerns. Nanotechnology involves manipulating matter at the molecular scale of 1 to 100 nanometers. The main tools used are transmission electron microscopes, atomic force microscopes, and scanning tunneling microscopes. Popular consumer products that use nanotechnology include L'Oreal Revitalift Eye cream and Solefresh nanosilver socks. While nanotechnology promises medical advances, some particles' safety effects are unknown. Tissue engineering uses nanomaterials to reproduce or repair damaged tissue.

3. Nanotechnology Foretold
Concept first
introduced by
American physicist
Richard P. Feynman
(1918-1988).

5. What is Nanotechnology ??
Nanotechnology is basically a science of
materials which has the following
features:
i.
Research and development at molecular
or atomic levels, with bond lengths
ranging between 1 to 100 nanometres.
ii. Invention of devices, and products which
have special functions or properties
because
of
their
small
size.

6. iii. Ability to control or manipulate the
matter on molecular or atomic scale.
iv. Nanomaterials
promise
to
revolutionize medicine and are
increasingly used in drug delivery or
tissue engineering applications.
v. Nanotechnology is also used to make
the changes in different species ,
whether it is a living or non living .

7. vi. These changes make them different from
their actual behavior.
vii. Some bring positive changes in the
species, which increases their efficiency.
viii. Basically, nanotechnology the ‘nano’
refers not to a thing but to the scale at
which the technology takes place

8. Tools in nanotechnology
The main tools used in nanotechnology
are three main microscopes :
Transmission Electron Microscope (TEM)
Atomic Force Microscope (AFM)
Scanning Tunneling Microscope (STM)

12. Why do some people think it’s bad ?
Many nano particles show unique chemical,
electrical, optical, and physical properties.
The great diversity of nano particles types
have made it difficult for scientists to make
general statements about the potential
safety hazards that nano particles might
show towards living organisms.

16. Ms. McCann tried this, and found the skin
around her eyes felt soft and looked shiny
at first but no lasting effects. She did not
find it comfortable.

18. L’Oreal RevitaLift Eye
The benefits in this product is supported by the
nanotechnology so it helps the skin and gives
vitamin D.

19. What are nanotechnology Socks ?
Nanotechnology
socks contain
nano particles of
silver. These
particles help kill
the bacteria that
makes our feet
smell. Many
people with
smelly feet will
benefit from this
technology.

21. Tissue Engineering
Nanotechnology can help reproduce or
repair damaged tissue. “Tissue
engineering” makes use of artificially
stimulated cell proliferation by using
suitable nanomaterial-based scaffolds and
growth factors. It combines biology,
medicine, engineering and materials
science to develop tissues that restore,
maintain or enhance tissue function.
