Micro-Swimmer_Robot_EN

Imagine robots that are so tiny that they can assemble themselves and swim through a patient’s arteries. Researchers at Drexler University in Philadelphia looked to bacteria for inspiration when designing these prototypes based on magnetic nanoparticles. The micro-swimmer robots could make some types of surgery unnecessary by unclogging arteries or delivering a drug to a precise location in the body. They should be ready for widespread use within four years.
