3. WHAT IS NANOTECHNOLOGY ?
• Nano is a Greek word which means
Extremely small.
• Nanotechnology deals with the size from 1-
100nm range.
• Nanotechnology is the art and science of
manipulating matter at the nanosize.

6. ORIGIN OF NANOTECHNOLOGY

Nobel prize winner –
DR. RICHARD FEYNMAN was the first scientist
who suggest that devices and material someday
will be fabricated to atomic specifications.
This concepts were first discussed in 1959 by him
in his talk “There's Plenty of Room at the Bottom”,
in which he described the possibility of synthesis
via direct manipulation of atoms.
In 1986,
Dr. K.ERIC DREXLER
introduce the term
NANOTECHNOLOGY
in his book “Engines of Creation: The Coming
Era of Nanotechnology.”

Nanoscale Approaches and Fabrication
Top-down
Approaches
Bottom-up
Approaches
Create smaller objects using
Larger objects
They arrange smaller
components in to more
complex.
Uses principles of molecular
recognition
Layer-by-layer self assembly

8. QUANTUM REALM
• Several phenomena become pronounced as the size of the
system decreases. These include statistical mechanical effects,
as well as quantum mechanical effects, for example the
"quantum size effect" where the electronic properties of solids
are altered with great reductions in particle size.
• This effect does not come into play by going from macro to micro
dimensions. However, quantum effects can become significant
when the nanometer size range is reached, typically at distances
of 100 nanometers or less, the so-called “Quantum Realm”.

21. ADDITIONAL INFO
• Carbon Nanotubes (CNTs) are tubes made of carbon with
diameters typically measured in nanometers.
• Graphene is an allotrope of carbon in the form of a single layer of
atoms in a two-dimensional hexagonal lattice in which one atom
forms each vertex. It is the basic structural element of other
allotropes, including graphite, charcoal, carbon nanotubes and
fullerenes.
• Buckminsterfullerene is a type of fullerene with the formula C60.
It has a cage-like fused-ring structure that resembles a soccer
ball, made of twenty hexagons and twelve pentagons, with a
carbon atom which has one π bond and two σ bonds at each
corner of the shape to create a universal vertex. 21
