  4. “It would take an elephant, balanced on a pencil, to break through a sheet of graphene the thickness of Saran Wrap.” http://nanularity.com/default.aspx y a1 a2 x SWNT carbon allotropes NSF-funded researchers Richard Smalley, Robert Curl (both of Rice University) and Harry Kroto (University of Sussex, UK; non-NSF funded) shared the 1996 Nobel Prize in Chemistry for the discovery of "buckminsterfullerene." James Heath, then a graduate student at Rice and now a faculty member at UCLA, also played a key role. nanotube

  5. Single-Walled Carbon Nanotubes Real timeNanotube length = 10 mm

  6. Bulk Gold = Yellow Nanogold = Red Size Matters

  7. Types of Nanomaterials Gold nanoshell

  8. Why is it so exciting? • Human Health • Gold nanoshells for cancer therapy • Environmental Health • Nanorust to clean drinking water Live (green)/Dead (red) assays shows where immunotarged gold nanoshells and a near infrared laser destroyed prostate cancer cells

  18. What is Nanotechnology? Nanotechnology is the creation of functional materials, devices, and systems through control of matter on the nanometer length scale, exploiting novel phenomena and properties (physical, chemical, biological) present only at that length scale. “If I were asked for an area of science and engineering that will most likely produce the breakthroughs of tomorrow, I would point to nanoscale science and engineering.” Neal Lane University Professor, Rice University Former NSF Director Assistant to President Clinton for Science and Technology
