What you need to know about nanotechnologiesWhere are nanotechnologies used?

Nanomaterials are already in use in a range of products you might come across, such as these:

Medicine

Nanotechnologies are already used in some important medical applications - and there are many more in the pipeline. For example, nanoparticles help treat cancer and parasitic infections.

Magnetic nanoparticles are used to diagnose conditions, avoiding the risks of surgery. Further nano research into replacement body parts and tissue engineering is currently underway.

From the pharmacy

Many products available in your local chemist claim to utilise nanotechnology, such as:

• nano zinc oxide and titanium dioxide to make clear, not chalky, sunscreen
• carbon nanocoating on the Wilkinson Sword Fx Diamond razor blade to help keep it ‘sharper for longer’
• nano-diamond plates on the Philips Tresemme Salon Shine Diamond hair straighteners to reduce friction
• nano silver in the cotton fibres of Agkilbact SoleFresh socks to protect against chilblains, cracked heels, itchy and smelly feet.

Food

Nanotech dietary supplements, such as Solgar coenzyme Q10 antioxidant supplement claims to be absorbed quicker and more easily.

Some food packaging is also being enhanced by nanotechnology.

Everin Pureseal Dee storage containers, for example, claim to kill harmful bacteria and prolong the shelf life of the food using nano silver.

Sports equipment

Some tennis racquets claim carbon nanotubes stiffen the shaft and head, thus creating a high strength-to-weight ratio.

Smelly sports towels could also be on the decline thanks to the alledged capabilities of products like the AgActive bath and sports towel which uses nano silver as antibacterial protection.

And some others

Nanotechnology is also used to give anti-bacterial properties by using nano silver in washing machines, fridges and clothes and to produce self-cleaning windows.
