  1. Nanotechnology:It really does “matter” By Arturo Aguilar Cluster 2

  2. A nano revolution • Nano-Tex has been selling nano-particle fabric treatments since 2001 • IBM Millipede Data Storage.  IBM is devoting one-half of its R&D budget to nanotechnology, including their revolutionary “millipede” data storage methodology.  • Basic nano research at the University of Washington has revealed the counter intuitive fact that E-coli bacteria cling more and more tightly the more surface pressure is applied to them. • A range of scientific fields have come together to comprise nanotechnology teams.  These fields include physics, engineering, biology, and chemistry, while ancillary fields like medicine, computing and so on are also deeply involved.  Each field independently was moving toward the study of the very small, and by coming together stunning new discoveries are being made. • While in 2000 there were about 10 private companies in nanotechnology, the number has grown to 1500 today, and may reach 2000 world wide by the end of 2004. • National governments are heavily backing research in nanotechnology, to the tune of perhaps $3.5 Billion in 2004

  3. A nano revolution (cont.)… • A range of scientific fields have come together to comprise nanotechnology teams.  These fields include physics, engineering, biology, and chemistry, while ancillary fields like medicine, computing and so on are also deeply involved.  • While in 2000 there were about 10 private companies in nanotechnology, the number has grown to more than 1500 today • National governments are heavily backing research in nanotechnology, to the tune of $3.5 Billion in 2004

  4. Fear of nanotechnology

  5. Fear of nanotechnology • The fears are not without logic. • Recent research shows that nanoparticles can pass through the blood-brain barrier in rodents. • Some are afraid of these machines being used for weapons of mass destruction.

  6. Gray goo threat • if we can build tiny machines from atoms that can in turn make new tiny machines from other atoms, they will begin to consume all the other atoms in their way in their quest to replicate, dissolving the world into a mess of "grey goo".

  7. Nanotubes • A number of companies are racing to scale up production of carbon nanotubes — molecule-size cylinders of carbon with unusual electrical, thermal and structural properties.

  8. Nanotubes • Very flexible • Strength: a value as high as 1.8 Tpa has been reported • Great conductors: they are the most highly conductive carbon fibres known

  9. In the future… • Oh, they’re only nanobots.
