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.
A single-atom engine is the latest example of how nano-technology can create machines to power tiny robots inside the body.
Hidden tools are making the world a safer place.
From tiny robotic doctors repairing your body to the latest climate change-tackling tools, nanotechnology is fighting an invisible battle on our behalf.
Is that a nano-bot in your guns, or are you just pleased to see me?
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…
