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
