gold nanoparticles have a long history–from stained glass in the 15th century to cutting-edge research in curing cancer. Talk about a precious metal! at least two products that you encounter in daily life that involved nanotechnology in their production? Although the term nanotechnology didn't gain popularity until the 1970s and 80s, the concept of manufacturing and using incredibly small objects has been around for decades. In fact, artists and engineers have been using nano-sized particles unwittingly for centuries. This section will introduce you to nano-related topics such as the production history of stained glass and rubber, Langmuir-Blodgett film, scanning tunneling microscopy, buckyballs, and the work of pioneering scientists Katherine Blodgett, Richard Feynman, and Richard Smalley.
