It’s a small but significant step for microscopic machines. Tiny motors have journeyed through a living animal for the first time, delivering a test cargo of gold nanoparticles directly into the lining of a mouse’s stomach.

Micromachines promise to revolutionise the diagnosis and treatment of certain medical conditions. Tiny spiders could repair blood vessels, for instance, while microrobots could swim through the bloodstream and build medical devices at sites of disease or injury. But until now, these devices have been tested in the lab using cell samples – not inside living animals. Read more on…
