Nanotechnology involves imaging, measuring, modeling and manipulating matter at the nanoscale of approximately 1 to 100 nanometers. It allows scientists to see and manufacture materials at the atomic scale using techniques like scanning tunneling microscopes. Nanotechnology has applications in electronics such as transistors and displays, energy with batteries and solar cells, materials like carbon nanotubes, and life sciences for targeted drug delivery and tissue regeneration. Advocates argue it will lead to stronger, lighter and cheaper materials while critics warn of potential environmental and health risks from nanomaterials. The future of nanotechnology is predicted to include electronic paper, morphing devices and smart contact lenses that will transform many everyday objects over the next century.

Editor's Notes

  1. In this presentation we are going to tell you, what actually nanotechnology is, how it is serving us in daily lives, what are its advantages and disadvantages and what the future of NT holds for us.
  2. so what is NT?
  3. by definiton as you can see ”it’s the art of manipulating matter at the nanoscale level”
  4. Now Here a question arises “how small the Nanoscale is?”
  5. 1. Its a bit difficult to realize how small the nano-scale is. To make things easier to get, we can say that one nanometre (nm) is one billionth of a metre. -2. Lets see some examples to make it clear In the picture on the right, we can see a man staring at his picked hair trying to figuring out the diameter of it, he will essentially come to the conclusion that a human hair is 100,000nm thick, while a DNA molecule is only 2 nms wide.
  6. We All Should care Because it can and most likely will bring revolution in the current industrialization and manufacturing processes.
  7. lets have a look how NT is leading us in different areas of expertise..
  8. e.g: in da field of electronics nanotransistors are becoming more nd more popular bcoz of it’s compactness.. If u are thinking that this is a single transistor then you need to reshape your thinking, bcoz this is a transistor box containing thousonds of transistors in it… Some other examples of nanoelectronics are Nanodiodes, OLEDs etc.
  9. The aapliances made with the help of nanoelectronics are getting its market share increasing and are becoming popular day by day due to the productivity and quality they have. Such as plasma Displays nd Quantum computing..
  10. 1-This is a nano-engineered battery, light in weight and flexible just like a paper. It can be rolled, twisted, folded or cut into a number of shapes with absolutely no loss of mechanical efficiency. Other energy suppliment examples with some change in their properties are fuel cells and solar cells
  11. 1-this rotating picture is actually a model of carbon nanotube, the strongest and stiffest materials discovered till to date. These tubes are the building block of almost all the NT objects. 2- Aerogel. The world’s lightest crystalline solid 3-and nano particles
  12. Apart from the engineering and science discussed so far, NT also has its applications in medical sciences 1- this picture shows the process of Targeted drug delivery.. Which will enable mankind to diagnose nd treat all the major diseases such as cancer, HIV etc. 2-. Artificial Retina and Tissue regeneration are the other examples of NT applications in life sciences..
  13. Although there are so many advantages to count about this incredible technology.. We are going to Highlight some of them……
  14. With NT, we can create unique materials and products which are: Stronger, Lighter, Cheaper, Durable and even Precise all at the same time
  15. 1- computers can become a billion times faster and a million times smaller.. 2- Automatic cleanup of Pollution.. 3- Manufacturing at almost No cost..
  16. Nothing is perfect in this World, so is NT..! Here are some of its disadvantages..
  17. Loss of jobs (in manufacturing, farming, etc) Carbon Nanotubes could cause infection of lungs Oil & Diamonds could become worthless Atomic weapons could be more accessible and destructive
  18. Now we are plugging into the future of Nanotechnology.
  19. 1- In future, you might be reading news on foldable electronic paper.. 2- This is the proto type of Nokia Morph concept phone based purely on NT.. 3- Contact lens that will let you check your blood sugar level by looking into a mirror. (It is expected to be coming in 5 years or so.
  20. This statement has obvious meaning that Nanotechnology is capable of changing the way almost everything is designed and made: from computers to clothing; from sports equipments to space ships and satellites; from cars to cancer therapies; from bridges to paint; and even objects and devices not yet imagined.
