•       2000 Years Ago – Sulfide nanocrystals used by Greeks and          Romans to dye hair            •       1000 Years Ago (Middle Ages) – Gold nanoparticles of different sizes used to produce different colors in stained glass windows •       1974 – “Nanotechnology” - Taniguchi uses the term                      nanotechnology for the first time •       1981 – IBM develops Scanning Tunneling Microscope                   •       1985 – “Buckyball” - Scientists at Rice University and University of Sussex discover C60 •       1986 – “Engines of Creation” - First book on  nanotechnology by K. Eric Drexler.       Atomic Force Microscope  invented by Binnig, Quate and Gerbe   •       1989 – IBM logo made with individual atoms                                                                   •       1991 – Carbon nanotube discovered by S. Iijima                                                              •       1999 – “Nanomedicine” – 1st nanomedicine  book by R. Freitas                                    •       2000 – “National Nanotechnology Initiative” launched
