Nanoparticles take a fantastic, magnetic voyage

Engineers have designed tiny robots that can help drug-delivery nanoparticles push their way out of the bloodstream and into a tumor or another disease site. The magnetic microrobots could help to overcome one of the biggest obstacles to delivering drugs with nanoparticles: getting them to exit blood vessels and accumulate in the right place.
