First Chapter Lesson-9: Nanotechnology.

At the end of this lesson-

  • 1. You will be able to explain Nanotechnology.
  • 2. You will be able to explain the uses of Nanotechnology.


Nanotechnology is a branch of technology where manipulation of matter on an atomic and molecular scale to create many new materials and devices. One nanometer (nm) is 10−9 of a meter.

Uses of Nanotechnology:

  • Computer Hardware Manufacture
  • Nano Robot
  • Electronic Devices
  • Fuel Cell
  • Packaging
  • Drug
  • Sports Tools
  • Space Exploration
  • Clothing Industry
  • Artificial Limbs

Advantages of Nanotechnology:

  •  Longer lasting, small in size and light weight devices can be manufactured with this technology.
  •  “Smart drug” is an implementation of nanotechnology that helps cure people faster and without the side effects.
  •  Revolutionary development in electronics industry with the invention of Nano transistor, Nano diode, plasma display etc.
  •  Batteries, fuel cells, and solar cells can be built smaller but can be made to be more effective with this technology

Disadvantages of Nanotechnology:

  • Atomic weapons can now be more accessible and made to be more powerful and more destructive. These can also become more accessible with nanotechnology.
  • Presently, nanotechnology is very expensive and developing it can cost you a lot of money.
