How it works

Nanotechnology works by three steps:
– manipulation
– create assemblers
– use replicators
Areas Affected By
Nanotechnology
Three Major Areas in Nanotechnology
Medicine
Environment
Computers
Nanotechnology and
Computers

Moore’s Law
– “The number of transistors on a CPU will
double in number every 18 months.”
Nanocomputers

Nanometer
– 1 nm = 1 billionth of a meter
– 1/500th width of a human hair

Transistors
– Not small enough
– Top Down  Bottom up
– Nanotubes
Nanotubes




Sheets of graphite rolled into a tube
50x stronger than steel
1-2 nanometers in diameter
Controlling
Nanocomputers

Using microwave energy and magnets
– Computers 200 – 500 times faster
– More reliable
– Cheaper
– 5-10 years
Ferroelectric Materials





Voltage changes polarity
Use like Binary
Non-Volatile RAM
Make computers lighter and smaller
Won’t need back-up batteries
Problems So Far….


Not going to happen overnight
Costs
– Production
– Programming
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
Medicine Intro

Nanotechnology has several possible
medical uses:
– A combatant against cancer
– Improve oxygen circulation in the body
– Molecular level tissue mapping
Cancer Research




Nanorobots identify tumor
Attach to the tumor
Release toxin for that type of tumor
Systems allow nanorobot to travel the
body
Circulation



Structures can house oxygen
Oxygen is released at certain
conditions
Possible to replace red blood cells
Tissue Mapping




Nanotechnology can provide a much
closer look at tissues
Tissues are fixed
Nanorobot scans tissue
Data processed by external computer
Nanotechnology and the
Environment
Advantages





Help clean up toxic spills
Detect pollutants
Expand available resources
Glean materials before they become
wastes
Reduce energy consumption on the
demand side
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.
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
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
Future of Environmental
Nano-technology




Solar cells
Nano-particle transportation
throughout the environment
Increasing food supplies
Reduce and clean up of pollution
