A nanometre (nm) is one thousand millionth of a meter. A single human hair is about 80,000 nm wide; a red blood cell is approximately 7,000 nm wide, a DNA molecule 2 to 2.5 nm, and a water molecule almost 0.3 nm. The term”nanotechnology” was created by Norio Taniguchi of Tokyo University in 1974 to describe the precision manufacture of materials with nanometre tolerances.
Nanotechnology is changing how we manage our environment offering replacements to aggressive cleaning chemicals, new solutions for infection control, seed enhancements, asset protection, public health and food hygiene. By manipulating molecules to create novel structures, devices and systems with outstanding properties, products are becoming lighter, stronger, healthier, smaller, more durable and safer.
