Bloodstream

Science fiction is fast becoming reality, with scientists in South Korea developing an astonishingly fast-moving remote-controlled microrobot designed to travel through the human bloodstream to deliver treatment directly to the organs that need it.

Researchers from the Max Planck Institute for Intelligent Systems, in Germany have been experimenting with real micro-sized robots that literally swim through your bodily fluids with the idea of delivering drugs or other medical relief in a highly-targeted way.
