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

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.

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.

4. Nanotubes and buckyballs are
nanoscale carbon structures that hold
many useful properties for manufacturing
and products.

•
•
Are stronger 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

• Carbon nanotubes are put on glass to
make it electrically conductive. The glass
stays clear because the nanotubes are so
small.

This module is one of a series designed to introduce faculty and high school
students to the basic concepts of nanotechnology. Each module includes a
PowerPoint presentation, discussion questions, and hands-on activities, when
applicable.
The series was funded in part by:
The National Science Foundation
Grant DUE-0702976
and the
Oklahoma Nanotechnology Education Initiative
