• Most widely used definition:
– Nanoscience is the study of phenomena and
manipulation of materials at atomic, molecular and
macromolecular scales, where properties differ
significantly from those at a larger scale.
– Nanotechnologies are the design, characterisation,
production and application of structures, devices and
systems by controlling shape and size at nanometre
scale.

, Nanoscale
• The size of the material ranging from 10nm to
100nm is called as Nano scale.
• Here the nanoscale is very important because
many physical and chemical properties starts
changing significantly when the size of the
material is below 100nm.
• This resulted in the birth of “Nano Science” and
“Nano Technology” which has great potential to
create many new materials and devices which
has great applications in many fields.

• Nanotechnology is the latest technology in which
the materials are used in nano size, i.e. atoms
are in the order of 1 to 100nm.
• Nanoscale: 1nm = 10-9m = 10-7 cm
• Nano means 10-9m i.e. a billionth part of a meter.
• Atoms are extremely small & the diameter of a
single atom can vary from 0.1 to 0.5nm
depending on the type of the element.
