Why is nanoscience important?
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

We will make materials that do not exists
