  1. Nanotechnology and Its Impact on Your Future Nanotechnology Research Center Georgia Institute of Technology Funding Improving Teacher Quality State Grants Program

  2. Why should you know something about Nanotechnology? • The National Science Foundation estimates that by the year 2015 there will be a need for 2 million workers worldwide in the fields of nanoscience and nanotechnology. • An additional 5 million workers will be needed in support areas for these fields. • By 2015, nanotechnology is expected to be a $3 trillion “industry”

  3. What is a “nano”? • A nano is one billionth of a meter or 10-9 m • A normal person can walk 32 kilometers or about 20 miles in one day. If a person were shrunk so that they were one nanometer tall, how long would it take them to walk the length of a dollar bill? • 24 years

  4. What is Nanotechnology? • The science of manipulating atoms and molecules to make new materials and devices. • Interdisciplinary – where science and engineering interconnect • Occurs at the 1-100 nanometer range • One nanometer is 10-9 meters or about 3 atoms long. For comparison, a human hair is about 60-80,000 nanometers wide

  5. Two Parts of Nanotechnology • Nanotechnology is often divided into two parts: • Nanoscience – where researchers learn about the chemical and physical properties of materials at the 1- 100 nanometer (nm) scale. Materials at 1-100 nm are called nanostructures. They are the smallest things that can be made. • Nanotechnology – where researchers develop and apply materials at this scale to develop new products or methods; i.e., turning nanostructures into useable tools and applications

  6. Unique Properties and Nanotechnology • Nanotechnology involves the manufacturing and application of instruments and materials that have unique properties because of their small size. • At the nanoscale, properties of materials behave differently and are said to behave under atomic and molecular rules. • Researchers are using these unique properties of materials at this small scale to create new and exciting tools and products in all areas of science and engineering.

  7. Nanofabrication • Top-down nanofabrication – start with large material and bring it down to the nanoscale • Bottom-up nanofabrication – start with individual atoms and build upwards to make a nanostructure

  8. Nanoscience Biomimicry • Ways scientists are attempting to mimic the wonders of nanoscience in nature: • sticky “feet” • strong spider silk • self-cleaning light reflecting butterfly wings • optical nanoscience • water collecting beetle backs • tough and light toucan beaks • and the list could go on and on. Taken from WebQuest Nanoscience in Nature by Jeanne Nye

  9. Nanotechnology is not New! Gold nanoparticles in glass are reflected as red Ancient stained-glass makers knew if they put finely ground gold or silver in the glass they would get beautiful colors. They used nanosized gold and silver particles. Optical properties change with the nanoscale.

  10. What are some applications of Nanotechnology?
