Nanoscience

What is nanoscience?

Refers to structures that are 1-100nm in size, of the order of a few hundred atoms.

Do nano particles have a high or low surface area to volume ratio

A high surface area to volume ratio, meaning smaller amounts are needed in comparison to normal sized particles

What is the diameter of a nanoparticle

1-100nm

What is the diameter of fine particles

100-2500nm

What is the diameter of coarse particles

2500-10000nm

What are the possible risks of nanoparticles?

They are so small, so it’s possible for them to be inhaled and enter the lungs, which may initiate harmful reactions and toxic substances could bind to them because of their large surface area to volume ratio

What are some applications of nanoparticles?

Medicine, cosmetics, sun creams and deodorants

Can nanoparticles be used as catalysts?

No
