Hadi Mohammadi presented on nanotechnology and its applications. Nanotechnology involves manipulating atoms and molecules to produce materials and devices at the nanoscale, which is one billionth of a meter. Some key applications discussed included using nanotechnology to generate renewable energy, improve electronic and information technologies, remediate environmental pollution, and advance nanomedicine for treating diseases like cancer. Specifically, nanomedicine shows promise for developing smarter drug delivery systems that can cure cancer faster with fewer side effects than traditional chemotherapy. In conclusion, nanotechnology will lead to many new small devices and materials that could help reduce the costs and impacts of cancer treatment.

 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.

7.  Nanotechnology deals with the manipulation of atoms and/or
molecules to produce materials, devices and even machines.

One nanometer is one billionth of meter(10 -9 m).
( like the prefix “kilo” indicates one thousand).
What are Nano &Nanotechnology?

8. Size of a Nanoscale !
A human hair is 100,000 nanometers wide.

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.

History

10. Applications
Some 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.

11. 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)

12. 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

13. 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).

14. 14Conclusion
1- Nanotechnology:
Will be creating many new smart and small materials , machines
and devices.
2- Nanomedicine
Will have so many applications which would reduce the cost and
minimize side effects of cancer .
