Nanoparticles are the future of medicine – researchers are experimenting with new ways to design tiny particle treatments for cancer

The COVID-19 mRNA vaccines put nanomedicine in the spotlight as a potential way to treat diseases like cancer and HIV. While the field isn’t there yet, better design could help fulfill its promise.

The nanoparticles in mRNA vaccines are nothing to fear: We interact with many useful, tiny particles every day

Some vaccine hesitancy is based on a fear of the nanoparticles used in mRNA vaccines. But humans have been interacting with nanoparticles for millennia, and we use nanotechnology-based devices every day.

Quantum dots that light up TVs could be used for brain research

These tiny nanoparticles might provide a new way to see what’s happening in the brain and even deliver treatments to specific cells – if researchers figure out how to use them safely and effectively.
Magnetotactic bacteria owe their special property to the magnetic nanoparticles they contain. Andy Tay

Magnetic bacteria and their unique superpower attract researchers

These single-celled organisms naturally respond to the Earth’s weak magnetic field. Scientists are untangling how it all works, looking to future biomedical and other engineering applications.

Destroying tumors with gold nanoparticles

Gold can be used to make jewelry, but also to fight cancer. Several clinical trials are currently underway in the United States where patients are being treated with gold nanoparticles.

No, nanoparticles in baby formula will not harm your baby

A widely publicised study that cast doubt on the safety of milk formula was misleading, based on dubiously reported studies and may have serious consequences.

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.

Small world: does ecology reach all the way down to the subatomic scale?

The advent of electron microscopy and nanobiology has moved our appreciation of the living world to unprecedentedly small scales – with entirely new benefits and potential pitfalls to consider.

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.

Nanoparticles in baby formula: should parents be worried?

Microscopic needle-like particles don’t seem like something you’d want to feed a baby. Whether safe or not, the way we deal with nanoscale food additives leaves plenty of other questions.
