  1. Nanotechnology

  2. What is nanotechnology? Extra info: A nanometre is a billionth of a metre. That’s half of the diameter of a strand of DNA! • The engineering of functional systems at the molecular scale • Building machines on the scale of molecules – a few nanometres wide • Involves the controlling and restructuring matter at the nanoscale • Endless possibilities regarding its uses

  3. The 4 generations of nanotechnology 2000 2005 2010 2015-2020

  4. How does nanotechnology work? • Quantum mechanics play a very important role in nanotechnology • Quantum physics is different from classical physics as substances at the nanoscale can behave erratically from what was expected • For example: • An electron can teleport—this is called electron tunneling • Substances that are insulators can become semi-conductors at the nanoscale • We can manipulate substances at the nanoscale to use them in various applications
