Conclusion
5
Atoms build molecules or form materials.
6
Remember that everything is made of atoms.
A stone, a pen, a video game, a TV, a dog and you
too are formed by atoms.
Nanotechnology deals with the manipulation of atoms and/or
molecules to produce materials, devices and even machines.
7
One nanometer is one billionth of meter(10 -9 m).
( like the prefix “kilo” indicates one thousand).
What are Nano &Nanotechnology?
Size of a Nanoscale !
A human hair is 100,000 nanometers wide.
8
A blood vessel is 10,000 nanometers in diameter.
A bacteria is 1000 nanometers wide.
A strand of human DNA is 2.5 nanometers in diameter.
particles created colors in the stained glass windows of
medieval churches.

History
ApplicationsSome of the most important applications:
1-Generates new forms of Energy
Produces Biofuel.
Converts Sun light to Solar cell.
Prepares modern Batteries.
3-Electronic and Information Technology
It’s used in OLEDs , smart cell phone
digital cameras and laptop computers.
2-Environmental Remediation
Can made materials that purification
water, soil, air from polluted form.
5- Nanomedicine
Is currently used to cure cancer.
4- Industrial applications It’s also used in food, sports, cosmetics,
Military, Automotive etc.

What Is Cancer? 11
How is cancer treated?
Surgery
Radiotherapy
Immunotherapy
Hormone therapy
Gene therapy
Chemotherapy
Cancer is abnormal cells division without any control.
Name of some general cancers:
Carcinoma (skin or tissues)
Sarcoma (bone, muscle)
Leukemia (bone marrow)
Central nervous system cancers
(brain & spinal)
What is chemotherapy? 12
A category of cancer treatment that uses chemical substances.
History of chemotherapy
The first use of drugs to treat cancer was World War I by Nitrogen
Mustards gas.
Types of chemotherapy:Classical treatment
Modern treatment
Disadvantages vs Advantages 13
Advantages
1- Nanotechnology can create
smart materials and drugs.
2- Help to cure people faster and
without the side effects.
3- More effective for producing
and Storage energy.
4-Procedures will be more fast,
smaller, portable, and easier to
administer.
Disadvantages
1- The possible loss of traditional
jobs.
2- Presently, nanotechnology is
expensive.
3- Create Atomic weapons
(more powerful &destructive).
14Conclusion
1- Nanotechnology:
Will be creating many new smart and small materials , machines
and devices.
2- NanomedicineWill have so many applications which would reduce the cost and
minimize side effects of cancer .
I WOULD LIKE TO CLOSE WITH
A HOMAGE TO :1- My uncle and cousin
2- Dear Morteza Pashai & Majide Bahrami
3- Every people whom has passed away by cancer.
