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.

Gold nanoshell


Why is it so exciting? through a sheet of graphene the thickness of Saran Wrap.”

  • 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

Why do electron beams give superior resolution to light rays?

Shorter wavelength!

What is nanotechnology
What is Nanotechnology?http://science.discovery.com/videos/brink-package-nano-water.html

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.”
