Uses of nanoparticles

Finding new ways to use nanoparticles is a really important area of scientific research
Here are some of the uses that have already been developed
- They have a huge surface area to volume ratio so they could help make new catalysts
- Nanomedicine is the idea that tiny particles, such as fullerenes, are absorbed more easily by the boy than most particles
- This means they could deliver drugs right into the cells where they’re needed
- Some nanoparticles have antibacterial properties
- They can be added to polymers fibres that are then used to make surgical masks and wound dressings and they can also be added to deodorants
- Nanoparticles are also being used in cosmetics
- For examples, they’re used to improve moisturisers without making them really dry

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 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
