    Nanotechnology Nanotechnology Presentation Transcript

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