The colour of gold nanoparticles in suspension varies according to the size of the nanoparticles.
Nanotechnology brings together multiple science disciplines to create devices that mimic the refinements of nature. It’s difficult – and exhilarating.
Nanotechnology isn't science fiction – you can find it in the latest TV screens, solar cells and tennis rackets.
Carbon nanotubes are one of the products created from engineering at the nanoscale.
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?
Keep the buzz. Lose the hangover.
A new pill may lower blood alcohol levels, helping a hangover and preventing alcohol overdose deaths.
There are nanometals in your washing machine.
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.
New research shows bees see a blue halo around flowers thanks to nanostructures on its petals.
New ways to prepare and test nanoengineered particles are helping us understand how they can target diseases.
The more we learn about bio-nano science, the easier it will be to design nanoparticles that behave like we want them to.
Achievement unlocked: Rewritable paper.
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.
Once the subject of fantastical stories, nanoscience is now changing the world as we know it.
Static electricity can cause more than just a bad hair day.
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.
Easy to transport and store, skin patches could soon replace needles for vaccination.
Postage-stamp sized patches that target vaccines to the immune system are now in clinical trials.
Who knew the steam engine would prove so useful?
A new technique can remove noise from tiny electronic circuits, raising hopes of extremely efficient electronics and quantum technologies.
Stoddart - one of three scientists to get THAT phone call.
The smallest motors ever made could one day have a huge impact on our lives.
We might think our technological innovations are driving us towards a cyborg future, but is it the brain doing all the work?
New research shows how adding memory to bacterial circuits could help us harness their computing power.
You’ll be amazed how much nanotechnology is found in the average house.
From the kitchen sink to the laundry and garage -- nanotechnology has already made its way into the average household.
Tastier salt, packaging that alerts you to food that has gone off and fish oil that tastes better – nanoparticles have lots of potential.
Some companies have used nano-titanium dioxide to make powdered sugar on donuts whiter.
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.
Scientists are using DNA to build exciting new nanotechnologies that could change everything from electronics to energy.
Treated with zinc nanoparticles, mung bean plants like these grew larger and produced more beans.
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.
