Why is nanoscience important?
![Page 3: Stone Age Copper & Bronze Age Iron & Steel Age Silicon AgeNanomaterials Age 1000-30 BC 2000 BC1000 BC20 th Century21 st Century Agricultural Revolution](https://reader035.vdocuments.site/reader035/viewer/2022062516/56649da05503460f94a8b5ce/html5/thumbnails/3.jpg)
When is Gold not Gold?
12 nm Gold particles looks Red!

A spherical particle that has a radius of about 8 atoms is a
nanoparticle
2 nanometers
But not a single atom!

Why this Change in Behavior? New Rules When We Go
Very Small
Easy to Cause Flow
If it’s Small it is Difficult to Cause Flow
?

200nm
Even More Than Size = New Behavior!We can form Molecules or Chains or Solids
made of Quantum Dots

But this is just the beginning! The biggest treasures
are yet to come

Material B
We will make materials that do not exists
today - anywhere
