Emergence
Figure 1.2: A nanocar made from a single molecule.
“…its arsenal includes
nanotechnological
transjectors…It can
control other machines.”
Figure 1.3: Arnold Schwarzenegger’s character mentions
nanotechnology in “The Terminator 3” movie.

Definition
“Nanotechnology is the understanding and control of matter at
dimensions of roughly 1 to 100 nanometers, where unique
phenomena enable novel applications.”
“Encompassing nanoscale science, engineering and technology,
nanotechnology involves imaging, measuring, modeling, and
manipulating matter at this length scale.”
National Nanotechnology Initiative, 2007

Brief History
The concepts of nanotechnology are not new to nature or to
mankind. An early example of a manmade nanoprocess is stained
glass.
Figure 1.7: Stained glass windows.
Figure 1.8: Picture of gold nano particles.

Brief History, Continued
Birth of Nanotechnology
• Professor Taniguchi of Tokyo Science
University used the word “nanotechnology”
to describe the science and technology of
processing or building parts with nanometric
tolerances.
•A nanometer is a unit of length in the metric
system, equal to one billionth of a meter. Figure 1.9:
Tokyo Science University.

Brief History, Continued
Dr. Richard P. Feynman
• “Why cannot we write the entire 24
volumes of the Encyclopedia
Britannica on the head of a pin?”
Dr. Richard Feynman, one of
America’s most notable physicists,
1918-1988.
Figure 1.11: Richard Feynman.

Brief History Continued,
Dr. Feynman, Continued
• “The problems of chemistry and
biology can be greatly helped if our
ability to see what we are doing, and
to do things on an atomic level, is
ultimately developed – a
development which I think cannot be
avoided.”
Surely You’re
Joking
Mr. Feynman!

Character

Atomic Scale
• A computer image of the nano
ice double helix.
• In the nano ice image, oxygen
atoms are blue in the inner
helix, purple in the outer helix.
Hydrogen atoms are white.

More History
Eric Drexler
• Coined the term “Grey Goo”…the
potential problem of self-replicating and
autonomous artificial intelligence
machines.

Cell Repair Machines
• “By working along molecule by
molecule and structure by
structure, repair machines will be
able to repair whole cells. By
working along cell by cell and
tissue by tissue, they…will be
able to repair whole organs…they
will restore health.” - Drexler, 1986

targeted cell repair.

Metrology
• Measurement of equipment is the cornerstone of
nanotechnology.

Buckyballs
• Three gentlemen—Harold Kroto from the
University of Sussex, Robert Curl and
Richard Smalley from Rice University—were
awarded the Nobel Prize in Chemistry in
1996 for their discovery of a new composition
of carbon, Carbon 60.
Figure 1.19: Carbon-60 buckyball is
shaped like a soccer ball.
Figure 1.20: Example of Nobel prize
diploma.

Fullerenes
• Carbon 60 was named after Richard Buckminster Fuller, who
went by the nickname “Bucky.”

Top-Down Approach
• Two approaches used in producing nanotechnology systems.
Top-down method is used by computer chip manufacturers.
Figure 1.23: Moore’s Law.

Bottom-Up Approach
•Bottom-up approach to manufacturing is analogous to the way
biological systems are made.
