NANOPARTICLES

What are nanoparticles

Really really tiny particles with a diameter of 1nm-100nm

What are the uses of nanoparticles

medicine, cosmetics, electronics, catalysts, surgical masks

What are the risks of nanoparticles

relatively new, suncreams

What is a key feature of nanoparticles

They have a large surface area to volume ratio

Why are nanoparticles useful as catalysts

Due to high surface area:volume ratio, much less of a material made of nanoparticles is needed, for the same effect as bigger particles

Why are nanoparticles useful in nanomedicine

So small and tiny, easily deliver drugs inside of our cells

Why are nanoparticles useful in electricity

Some have delocalied electrons and can conduct electricity and be used in tiny computer chips

Why are nanoparticles useful in surgical masks

Silver particles have good antibacterial properties, infuse them in surgical masks and reduce chance of infection

Why is nanoparticles being new a risk

We don't have any info on the harm they could cause and the effects they have on our body
Need to be tested thoroughly before being sure

Why is using nanoparticles in suncream a risk

They do have better skin coverage and are good at protecting us from harmful UV rays
HOWEVER
We don't know if they're getting into our body or not and possibly damaging our cells

Why is getting rid of nanoparticles a risk

Throwing them into the sea we have no clue or evidence on what happens once they get into the sea, they could be damaging environments
