Nanotechnology:
A Future Green Technology
What? / Why?
• Science of the extremely tiny
• Control of matter on the atomic and molecular scale
below 100 nm
• Fabrication of device size within below 100 nm
• Field of applied science, technology, engineering, etc
• Field of pharmacy, medical, health, etc
• Field of safety, economy, law, etc
• Field of “A Future Green Technology”

A Future Green Technology
How to Prepare?
There are 3 approaches of nanotechnology
to prepare the nanomaterial and its
applications:
1) Top-Down
2) Bottom-up
Traditional engineering
techniques such as
machining and etching are
used at very small scales,
without atomic level
control.
Structures are built up atom
by atom which assembles
themselves chemically using
principles of molecular
recognition.
3) 1+2

History?
• 1959 - Richard Feynmen gave a historical speech, “There’s Plenty
of Room at the Bottom” that made people to start thinking
seriously about the possibilities of nanotechnology
• 1965 - Gordon E. Moore, “the number of components in integrated
circuits should double every year”
• 1970 - Leo Esaki pioneered the technology on manmade
semiconductor structure such as superlattices, showing unknown
properties
• 1974 - Norio Taniguchi in his paper “On the Basic Concept of
Nanotechnology” to describe the ultrafine machining of matter
• 1975 - Various concept based on manipulation of metal in nano
level was proposed, such as quantum dots, containers are able to
confine one or more electrons
• 1981 - Gerd Binnig and Heinrich Rohrer invent the scanning
tunneling microscope (STM), a device that can create images of
the nano world

History?
• 1985 - Prof. Harold Kroto, Richard Smalley and Robert Curl
discover fullerenes, football-shaped molecules made up of sixty
carbon atoms.
• 1986 - Eric Drexler proposed bottom-up nanotechnology with the
publication of his book, “Engine of Creation”.
• 1989 - Don Eigler, a physicict at IBM Research Division’s Zurich
Laboratory, succeeds in manipulating atoms using STM, providing a
concrete demonstration of how atoms could be assembled.
• 1991 - Prof. Sumio Iijima from Meiji University (Japan) and NEC
research fellow discovers carbon nanotubes (CNTs), hollow tubes
of several nanometers derived from graphite sheets.
• 2003 - Prof. Tetsuo Soga from NITech (Japan) has synthesized
CNTs from Camphor Oil.
• 2005 - M. RUSOP, etal. from UiTM (Malaysia) has synthesized
CNTs from Palm Oil and Coconut Oil.
