Scientists invent nanorobots that can repair brain aneurysms | Live Science
Tiny robots much smaller than blood cells could deliver clot-forming drugs where they're needed most, a study in rabbits suggests. The tech has yet to be tested in humans.
There can also be a need to take blood thinners indefinitely to avoid clots, said Qi Zhou, a research associate in bioinspired engineering at the University of Edinburgh and the co-author of a new paper describing the nanorobots. "Our remotely controlled magnetic nanorobots provide a more precise and safer way to quickly seal off cerebral aneurysms without using implants," Zhou told Live Science. Each bot consists of a magnetic core, a clotting agent called thrombin that treats the aneurysm, and a coating that melts when lightly heated, in order to release the medication.
