Nanotechnology is not New! Gold nanoparticles in glass are reflected as red Ancient stained-glass makers knew if they put finely ground gold or silver in the glass they would get beautiful colors. They used nanosized gold and silver particles. Optical properties change with the nanoscale.

Top-down nanofabrication start with large material and bring it down to the nanoscale. Bottom-up nanofabrication – start with individual atoms and build upwards to make a nanostructure. Nanofabrication

Nano Projects. 1.Do some electroplating. 2.So nanosocks really keep your feet from smelling. How and why? 3.Synthesis Nano particles. 4. Do pants with nanocoating actually shed water and stains better?
