2. Introduction
• Nanotechnology and nanoscience are the
study and application of extremely small
things and can be used across all other
science field such as Chemistry , Biology,
Physics, Material Science ,Engineering.
Or
• It is a science engineering and technology
conducted at the nanoscale, which is
about 1 to 100 nm.
3. How it Started!
• The idea and concept behind nanoscience
and nanotechnology started at 1959 on the
talk entitled:- “There’s plenty of Room at
the Bottom”, by the physicst Richard
Feynman.
4. Fundamental concept
• Nanoscience involves the ability to see and
to control individual atoms and molecules.
• The microscope needed to see things at the
nanoscale were invented recently; the right
tools include :- The scanning tunneling
microscope and atomic free microscope.
• The properties involves :- higher strength,
lighter weight , increased control of light
spectrum, greater chemical reactivity.

6. Application.
• In the field of Medicine : Nano medicine
monitor , repair and control of human biological
systems at molecular level using engineered
nano devices.
– Wide application in drug delivery
– Visualization:- Contrast agents images such as Ultra
sound and MRI have improved contrast.
– Nano -sensors:- magnetic nano particles bound to a
suitable antibody used to label specific molecules,
structure.
– In tissue engineering.
– Nano filters will create impurity free drugs.
7. • Nanobiotechnology.
– Approach to biology allows scientists to
imagine and create systems that can be used
for biological research.
– Use of microorganisms to synthesis functional
nanoparticles.
– Nanospheres can be coated with fluorescent
polymers.
8. • Green nanotechnology .
– aim at enhance the environmental
sustainability thus result in product
sustainability.
• Energy application of nanotechnology.
– Increasing the efficiency of energy
production.
– Increasing use of alternate sources.
• Industrial application.
– Food : high quality and safe food
– Consumer goods: use of engineered
nanofibers in textile industries.
9. Conclusion.
• 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
