  3. The meaning of the word nanotechnology Nano comes from the greek word meaning ‘dwarf’ Technical: refers to a reduction factor 1 nm= 10-9 = one billionth of a meter Nanotechnology in food (PHL & HELHA group 6)

  4. The meaning of the word nanotechnology Nanotechnology is defined as:“ the investigation for phenomena and handling/process of materials at atomic, molecular and macromolecular scale.” Macromolecular scale= nanoscale= sizes of 0,1 to 100 nanometers. Nanotechnology in food (PHL & HELHA group 6)

  5. The meaning of the word nanotechnology Official Starting point of nanotechnology: the lecture ‘Plenty of room at the bottom’ of Richard Feynmann in 1959. However in 1905 Albert Einstein already found that the diameter of a sugar molecule was around 1 nm. Already used for years: colored glass Nanotechnology in food (PHL & HELHA group 6)
