Scientists have developed nanorobots that can repair brain aneurysms with unprecedented precision. These tiny robots are smaller than blood cells and can deliver clot-forming drugs directly to the site of the aneurysm, preventing devastating strokes.
The technology has been tested only in rabbits so far, but it could potentially become an alternative to current treatments for human patients. Aneurysms occur when the wall of an artery weakens and balloons out, and they can be life-threatening if left untreated.
The nanorobots are remotely controlled using a magnetic field, allowing them to be guided to the aneurysm site. Once in place, they release clotting agents that quickly form a stable blockage, preventing further bleeding.
In a recent study published in the journal Small, researchers tested the biocompatibility of the nanorobots in human cells and used them to treat artificially induced aneurysms in three rabbits. The results showed that the robots were successfully guided to the aneurysm site and effectively blocked it off completely.
While more testing is needed, the technology has the potential to revolutionize the treatment of brain aneurysms, providing a safer and more precise solution for patients.
