Why nanotechnology is more than just a buzzword

Nanotechnology brings together multiple science disciplines to create devices that mimic the refinements of nature. It’s difficult – and exhilarating.

The BS and the science of nanotechnology

Last week, Elon Musk 'called BS' on nanotechnology. And it threw up an important question: just what is nanotech, and is it more hype than science?

Silver nanoparticles in clothing wash out – and may threaten human health and the environment

Many socks, towels and other textiles are treated with silver nanoparticles to kill germs and odors. When the silver washes out, it can pollute waterways. Two chemists propose a way to collect it from wastewater.

Reprintable paper becomes a reality

Coating paper with an inexpensive thin film can allow users to print and erase a physical page as many as 80 times. That reduces both the cost and the environmental effects of paper use.
Static electricity can cause more than just a bad hair day. Ken Bosma

Static electricity’s tiny sparks

These mini lightning bolts have been known for millennia. Understanding static electricity at the atomic level opens the door for new technologies – as well as ways to cut down on the tiny zaps.

No big deal: there is little to fear from nanoparticles in food

Two new studies from Food Standards Australia and New Zealand show there's no evidence that nanoparticles in food present a health risk, but there's more research to be done.

How nanotechnology can help us grow more food using less energy and water

Growing enough food to feed 9 billion people by 2050 will require huge amounts of energy and water. Using nanoparticles to boost plant growth and yield could save resources and reduce water pollution.
