Nanotechnology Takes Off - KQED QUEST

Notes:

A nanometre if is a billionth of a metre.

At a nano-scale, material behave differently. Sillicone glows different colours depending on the size of the piece of sillicon you are looking at.

Taking inspiration from natural motors in bacteria and cells.
E.g. The tiny motors a sperm uses to propell itself.

Future:

Tiny devices to clean arteries and filter water.

Past:

A heating and cooling process is used to stain glass windows by altering the size of tiny crystals in the glass.

Current:

Solar energy.
Instead of using sillicone and crystal, scientists are trying to create cheap, durable polymers that conduct heat better than sillicone and crystal
