Nanoparticles
________ are also being used in cosmetics.
surface area
The ________ to volume ratio is an important factor as it can affect the way that a particles behaves.
Nanoparticles
________ have a very high surface area to volume ratio, this means the surface area is very large compared to the volume.
nanoparticle size
1nm to 100nm
Surface area
______to volume ratio
Nanoparticles used
in sun-creams, give better skin coverage than normal
Effects of nanparticles
non-known at the mometn
Nanoparticles commercial uses
cosmetics such as moisturisers
Uses of nanoparticles
good for catalysts because of there large surface area to volume ratio
Some nanoparticles
______could conduct electricity
Silver nanoparticles
have antibacterial properties
Nanomedicine
idea that tiny particles are absorbed easily by the body
Bad nanoparticles
might damage the environment
Nanoparticles ratio explained
as particles decrease in size, the surface area increases in relation to volume
Properties differ
_____depending on whether it's a nanoparticle or in bulk
