Nanoparticles?-what is it

Nanoparticles-what is it?

Any particle with a size between 1-100 nm is called a nanoparticle.

Due to their small size, they can penetrate through surfaces easily. And they have a hush surface area/volume ratio, so should properties different than bulk like color, catalytic properties, etc.
