Nanoscience
Size and shape dependent properties
NanoScience : The science of manipulating atoms and molecules to make new materials and devices.

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.

Challenges
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?
