Nanoparticles

Question 1

What are nanoparticles?

Answer 1

1. Simply tiny particles

Question 2

How big are nanoparticles?

Answer 2

1. Diamater of between 1 nanometer and 100 nanometers.
2. They contain only a few hundred atoms.

Question 3

Uses of Nanoparticles?

Answer 3

1. They have a huge surface to volume ratio, so they could help to make new catalysts.
2. Nanomedicine is on the rise - the idea is that tiny particles are absorbed more easily by the body than most particles. This means they could deliver drugs right into the cells where they’re needed.
3. Some nanoparticles conduct electricity, so they can be used in tiny electric circuits for computer chips.
4. Silver nanoparticles have antibacterial properties. They can be added to polymer fibres that are then used to make surgical masks and wound dressings and they can also be added to deodorants.
