HideShow resource information

Nanoparticles-

  • Very small particles 
  • Can be measured at around 1-100nm
  • Have a huge surface area to volume ratio
  • Each nanoparticle contains a few hundred atoms

Uses:

  • Chemical industry: used as catalysts due to the huge surface area to volume ratio
  • Cosmetics: deodrants/ sun tan cream- does not leave behind white marks
  • Medical: Drug delivary, anti-viral or anti-fungal treatment
  • Construction: used to create strong but light material e.g. aircrafts-
