Like the implied visualization

Researchers at the Chinese University of Hong Kong (CUHK) have developed a corkscrew-shaped microrobot that can swim through blood vessels and help drugs unblock clots more effectively. CUHK's Li Zhang said the robot's helical structure mimics a propeller's to enable drug delivery, while non-drug payloads also are possible. The researchers employ magnets to rotate the robot's rotor and to drag it through a blood vessel, while Doppler tracking guides its path by reflecting sound waves off blood cells. Said Pierre GĂ©lat of University College London, “The ability that they have to steer the robot in in-vitro environments is quite nice. The challenges are in finding out whether this will fulfill unmet clinical needs further down the line, and how you get there as well.”
