 Defination:- The science,engineering & technology related to the understanding & control of matter at the length scale approximately 1 to 100 nanometer.

 Start with centimeter A centimeter is about the size of a bean  Now divide it into 10 equal parts Each part is a millimeter long. About the size of a flea.  Now divide that into 10 equal parts Each part is 100 micrometers long. About the size (width) of a human hair  Now divide that into 100 equal parts. Each part is a micrometer long. About the size of a bacterium.  Now divide that into 10 equal parts Each part is a 100 nanometers long. About the size of a virus.  Finally divide that into 100 equal parts. Each part is a nanometer. About the size of a few atoms or a small molecule

 Faster  Lighter in weight  Cheaper  Require less space  More energy efficient

 Copper is opaque substance become transparent.  Platinum is inert material become catalyst.  Aluminium is stable material become combustible  Silicon is insulator material become conductor.

Manufacturing at the nanoscale or to get nanomaterial is called nanomanufacturing Two types of manufacturing 1)Top down 2)Bottom up

1)Top down:- It reduce large piece of material all the way down to nano scale. This process require larger amount of material.

2) Bottom up:- It creates products by putting together smaller piece. It is a self assembling of material.

 Electronics  Health & Medicine  Transportation  Energy and Environment

 Nanosensors are used for collecting,processing and communicate massive amount of data with minimum size,weight and less power consumption.  Smaller Transistor  Smaller Memory  Smaller Circuitry

 Nano medicine has potential to improve diagnosis & treatment of cancer,aids,alzheimer & diabetes.  Nanofilter will help create impurity free drugs.  Nanotechnology that can regrow bone and organ.

 Carbon based fibers which are 100 times stronger than steel and one sixth the weight.  Nanocoating of metallic surface provide super harding,low firction & corrosion protection.  Faster,cheaper & safer transformation.

 Nanocrystal,nanofilter,nanosensor are being used for cleaning drinking water.  Nanomaterial based cosmetics are provide greater clearity and scan care.

 Super computer  Energy storage batteries  Baseball bat Carbon nanotube baseball bat Shocks with silver nanopartical
