Molecular motors. That's how scientists teach nanoparticles to rotation around on cue

I am a hardened robot with distant control – Lem wrote in “The Robot Fairy Tales”. Today, it's not amazing to power robots. Their miniaturisation remains a challenge, while maintaining precise traffic control. This condition is met by alleged molecular motors, machines as tiny as single particles. Dr Wojciech Danowski and Dr Joanna Jankowska from the Faculty of Chemistry at the University of Warsaw are taking care of them.
