Nanotechnology

  1. 1. Nanotechnology<br />
  2. 2. What is Nano?<br />Nano means one billionth.<br />The Scale of “Nanoscale”<br />1 nm = 0.000000001 m<br />
  3. 3. What is Nanotechnology?<br />Nanotechnology is the creation and use of materials or devices at extremely small scales.<br />Nanotechnology - Deals with molecules between one and one hundred nanometers in diameter. Manipulating individual atoms and manufacturing from the bottom up.<br />
  4. 4. Nanotechnology Foretold<br />Concept first introduced by American physicist Richard P. Feynman (1918-1988)<br />Calculated that an encyclopedia set could be compressed to fit the head of a pin.<br />Predicted several aspects in today’s nanotechnology<br /><ul><li>Advanced microscopes
  5. 5. Developments in fabrication methods
  6. 6. Possibilities of atom-to-atom assembly</li></li></ul><li>History of Nanotechnology <br /><ul><li>As early as 500 AD, glass artisans were making stained glass windows with vibrant reds and yellows.
  7. 7. These colors were much more luminous and durable than dyes could produce, and were the products of “coinagemetal” nanoparticles imbedded in the glass.
  8. 8. As these nanoparticles get smaller, </li></ul>the colors shift from red, through yellow and green, to blue.<br />
  9. 9. Modern Nanotechnology - Investment <br />Investments in nanotechnology are on the rise.<br />These advances are in both basic university-basedresearch, as well as industry.<br />Many of these advances use nanoparticles in some form or other.<br />
  10. 10. A demonstration on the molecular level<br />A nano-motor manipulated by two laser beams<br />
  11. 11. Positive Effects on Society<br />Nanomachines could allow for cleaner energy production<br />Nanomachines in the blood stream patrolling for viruses<br />
  12. 12. Medical Applications<br />Nanomachinescould travel through the bloodstream<br />
  13. 13. Future with Nanotechnology<br />A nano-gear<br />A nano-universal-joint<br />
  14. 14. Future with Nanotechnology<br />A nano-Bearing<br />A “nano-factory”<br />
  15. 15. Applications<br />Researchers intend to developed adequate fabrication methods for commercial uses:<br /><ul><li>Cosmetics
  16. 16. Clothing
  17. 17. Encoding in Fiber Optics
  18. 18. Inhibition of Spontaneous Emission
  19. 19. Paints
  20. 20. Fabrics
  21. 21. Integrated Optics Components
  22. 22. Computer Circuits*</li></ul>The Blue MorphoRhenetor Butterfly:<br />The Blue MorphoRhenetor Butterfly is the focus of our project as we study the photonic crystals found on the scales of the wings. <br />
