Does size matter? Yes, Nano even better!

    "Nanotechnology is the idea that we can create devices and machines all the way down to the nanometer scale, which is a billionth of a meter, about half the width of a human DNA molecule." ~ Paul McEuen

Nanometer scale which is a billionth of a meter. Hard to imagine right! Yes very difficult.

Here is a video which will help you all to imagine-

Now, that you know how small Nano is... below is a picture defining Nanotechnology.

EMINENT PERSONALITIES aka FATHERS OF NANOTECHNOLOGY

L to R: Richard Feynman, K.Eric Drexler, Dr. Chad Mirkin.

NANOPARTICLES

• A Nanoparticle is a microscopic particle with dimension between 1 to 100 nm.
• The basic idea that goes in the making of Nanoparticle is reducing the size of an atom which in turn changes it's properties namely- Physical, Chemical, Optical, Thermal, Mechanical,etc.
• Nanoparticles are of different shapes and dimensions(1D, 2D, 3D)
