2. How it works Nanotechnology works by three steps: manipulation
create assemblers
use replicators

3. Areas Affected By Nanotechnology

4. Nanotechnology and Computers
Moore’s Law
“The number of transistors on a CPU will double in number every 18 months.”

5. Nanocomputers Nanometer Transistors 1 nm = 1 billionth of a meter
1/500th width of a human hair
Transistors
Not small enough
Top Down  Bottom up
Nanotubes

6. Nanotubes Sheets of graphite rolled into a tube
50x stronger than steel
1-2 nanometers in diameter
Controlling

7. Nanocomputers Using microwave energy and magnets
Computers 200 – 500 times faster
More reliable
Cheaper
5-10 years

8. Ferroelectric Materials
Voltage changes polarity
Use like Binary
Non-Volatile RAM
Make computers lighter and smaller
Won’t need back-up batteries

9. Problems So Far…. Not going to happen overnight Costs Production
Programming

10. Nanotechnology and Medicine
Engineering of functional systems at the molecular scale
Hybrid of chemistry and engineering
Purpose of nanotechnology is to align individual atoms into the desired structure

11. Medicine Intro Nanotechnology has several possible medical uses:
A combatant against cancer
Improve oxygen circulation in the body
Molecular level tissue mapping

12. Cancer Research Nanorobots identify tumor Attach to the tumor
Release toxin for that type of tumor
Systems allow nanorobot to travel the body

13. Circulation Structures can house oxygen
Oxygen is released at certain conditions
Possible to replace red blood cells

14. Tissue Mapping
Nanotechnology can provide a much closer look at tissues
Tissues are fixed
Nanorobot scans tissue
Data processed by external computer

15. Nanotechnology and the Environment

16. Advantages Help clean up toxic spills Detect pollutants
Expand available resources
Glean materials before they become wastes
Reduce energy consumption on the demand side

17. Nanoenergy and a Green Economy
Harness solar energy with nanocells
Membranes to convert sunlight into energy
High efficiency solar cells
Nano-photosynthesis
Nanotechnology will be pollution free and use one-hundred percent recycled materials.

18. Food Production
Nano-photosynthesis produces paper, sugar, and other materials to ease real environmental products
Super efficient nanobots will make food last longer and have more minerals and vitamins.
Maintain greenhouses

19. Pollution One hundred percent biodegradable and recyclable products
Reduction of CFC’s and other toxic materials
Reduction of smog and acid rain
Prevention of global warming by using less fossil fuels

20. Future of Environmental Nano-technology
Solar cells
Nano-particle transportation throughout the environment
Increasing food supplies
Reduce and clean up of pollution
