Nanoparticles

Nanoparticles

1. Properties

   • Nanoparticles have diameter between (1*10^-9) and (1*10^-7)
   • Nanoparticles only have a few hundred atoms
   • Nanoparticles have large surface area to volume ratio

2. Uses

   • Nanoparticles can help to make new catalysts as they have high SA to Volume ratio
   • Nanoparticles are absorbed more easily by the body; drugs can be delivered wherever it wants to
   • Some nanoparticles conduct electricity so can be used in computer chips

3. Effects

   • Nanoparticles effect on health is not fully known
   • Since long-term effects are not known, labels are expected to say nanoparticles if product is contained with it
