  Introduction
  •
   Usage of nanotechnology is very ancient in Greek and Chinese 
  civilzation  . one of oldest famous app. Is the Greek cup “Lycurgus” 
   
  which change the color according to angle of falling light [was used 
  in the manufacture of nano-particles of gold mixed with glass ]. also 
  “ Damascene swords ” they used wootz steel made in India [ this     
  sword known with his hardness and flexibility ].
