How to
Manufacture
Nanotechnology
1. Top Down technique uses large machines to make the nanostructures from larger materials
• Example: Photolithography to make Computer
Processor Chips cc by Via Gallery
2. Bottom Up technique uses chemical and physical interactions to make nanostructures without guidance
• Example: Catalyst to make Carbon Nanotubes

3. Smart Materials are manufactured goods that react to some outside forces. Crystals can expand and contract with electricity, metals can retain a shape memory, liquids can move with magnetic fields, and surface cracks can heal themselves.
Updated September 2011 cc by Thomas Shahan
Self-Healing Materials have micro- or nano-size capsules of chemicals in the structure. When a crack forms, it ruptures the capsules, releasing the chemicals to react and heal the material.
Products can now heal themselves

Ferro Fluids are liquids with nanoscale magnetic particles suspended. This makes the whole fluid react to a magnetic field but turn back into a liquid without it.

Nanotube
• Are stronge r than steel
• Can be made to be very conductive
• Can be made to be nonconductive
• Are good heat conductors in one direction
• Are good heat insulators in the other direction
Updated September 2011
• Carbon nanotubes are put on glass to make it electrically conductive. The glass stays clear because the nanotubes are so small.
