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.
As the components in electronic devices are shrinking to the nanoscale, even a single atom out of place can disrupt their function. But this also presents an opportunity to make them even better.
One of great challenges of the 21st century has been to develop ways to manipulate matter on smaller and smaller dimensions. As the great physicist Richard Feynman noted in his famous 1959 lecture, “There’s…
The idea of doctors deploying miniscule robots in your body to diagnose and treat medical conditions is closer to reality today with the development of artificial muscles small and strong enough to push…
Scientists have invented new stick-on ‘tattoos’ that track human heart, brain wave and muscle activity and could one day replace cumbersome medical monitors. Known as an epidermal electronic system (EES…
That tangled collection of chargers could one day be obsolete, as Australian researchers report a breakthrough that brings us closer to a world where gadgets are recharged every time you press them. Scientists…
Scientists have developed tiny particles capable of taking large doses of anti-cancer drugs right to a tumour’s doorstep, opening the way to a new generation of more effective treatments. Nanotechnology…
