Uses of Nanoparticles

• Finding new ways to use nanoparticles is a really important area of specific research. Here are some uses that have already been developed:

  • They have a huge surface area to volume ratio, so they could help make new catalysts
  • Nanomedicine is a hot topic. The idea is that tiny particles (such as fullerenes) are absorbed more easily by the body than most particles. This means they could deliver drugs right into the cells where they're needed
  • Some nanoparticles conduct electricity, so they can be used in tiny electric circuits for computer chips
• Finding new ways to use nanoparticles is a really important area of specific research. Here are some uses that have already been developed:

  • Silver nanoparticles have antibacterial properties. They can be added to polymer fibres that are then used to make surgical masks and wound dressings and they can also be added to deoderants
  • Nanoparticles are also being used in cosmetics. E.g. they're used to improve moisturisers without making them really oily
• The effects of nanoparticles on health aren't fully understood
• Although nanoparticles are useful, the way they affect the body isn't fully understood, so it's important that any new products are tested thoroughly to minimise the risks
• Some people are worried that products containing nanoparticles have been made available before the effects on human health have been investigated properly, and that we don't know what the long-term impacts on health will be
• As the long-term impacts of nanoparticles aren't known, many people believe that products containing nanoscale particles should be clearly labelled, so that consumers can choose whether or not to use them
• Nanoparticles are being used in sun creams as they have been shown to be better than materials in traditional sun creams at protecting skin from harmful UV rays. They also give better skin coverage than traditional suncreams
• In suncreams, it's not yet clear whether the nanoparticles can get into your body, and if they do, whether they might damage cells. It's also possible that when they are washed away they might damage the environment
