10 Interesting Facts About Nanotechnology

Nanotechnology is ek_4_crystalverywhere. The newest field of robotics and technology research promises to change the way people lives, heals, interacts with other people and objects. But most individuals don’t know much about it… So here’s ten facts that will make it more appealing and fascinating for everyone.

  • A nanometer is as small as the width of a strand of a DNA – which is itself invisible to the naked eye.
  • Nanotech has been used for centuries even though mankind never realised it, until now. Infact, in Medieval times, painters used to use nanocrystals to paint the stained glass windows by heating and cooling the glass surface.
  • Materials tend to display strange and unusual properties when observed at the nano scale. For example, their melting and cooling points, color and even transparency significantly differ from larger blocks of the same material.
  • Carbon fiber and metal blends are being used to detoxify hazardous waste as they are easily soluble, allowing them to find and destroy these chemicals in nano form.
  • In the USA, this technology is already being used to purify water from metals, solvents and petroleum waste.
  • Nano particles are also being used commercially in many products like food, cosmetics and others as they result in brighter colours, richer flavours and also less wastage.
  • According to a recent report, the use of nano particles in commercial manufactured goods has already reached $1.6 trillion in the year 2013.
  • On the minus side, these same nano particles can enter your brain, find their way into the blood streams and even enter the cells to destroy them. This can result into lung damage and brain damage. Studies have been conducted that have confirmed these theories.
  • An IBM engineer by the name of Don Eigler became the first man in the history to control the movement of an atom using the atomic force of a microscope. He was able to achieve this feat in the year 1989 only.
