Nanoparticles occur naturally in some foods, and others have them added.
Nanoparticles are extremely tiny particles, with external dimensions smaller than 100 nanometres (0.0001 of a millimetre). Here’s what we know about nanotechnology in food.

Phosphorene nanoribbons are like tagliatelle, but carry the potential to boost battery capacity by 50%.
Gold is one of 12 confirmed elements on the periodic table whose discoverer is unknown.
Nanotechnology and materials are the source of countless innovations, but we don’t accurately know how they are affecting humans and the environment.

After declining for nearly a decade, the number of hungry people in the world is growing again. Climate change, which is disrupting weather patterns that farmers rely on, is a major cause.
Nanomedicine could scupper the need for TB patients to take multiple daily tablets with toxic side effects.
The reason that nanoparticles hold such hope for TB treatment is that they can be carefully targeted.
There are countless nanoscopic architectures in nature, creating iridescence, sticky feet, magnetic navigation – and more.
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.
