Scientists from the University of Edinburgh have developed nanorobots that can prevent strokes by delivering medication to brain aneurysms. Research results presented In the little magazine.
The experiment was conducted on rabbits in which aneurysms were artificially created in the carotid arteries. An aneurysm is an abnormal expansion of the arteries that occurs due to weakening of the arterial wall. Pathological expansion of the vessel leads to thinning of the arterial wall, which is fraught with serious complications such as stroke.
The nanorobots created to treat aneurysms are 295 nanometers in diameter. A typical virus is about 100 nanometers wide, and most bacteria are about a thousand nanometers wide. Each nanorobot consists of a magnetic core, thrombin, which is used to treat aneurysms, and a shell that dissolves with gentle heat to release the drug.
Nanorobots are sent to the aneurysm and dissolve its membranes using a magnetic field. This prevents damage to body tissues, as the exposure temperature does not exceed 50 degrees Celsius.
Scientists delivered nanobots into the animals’ bloodstream in areas just above the aneurysm. The nanobots form a stable clot that does not block blood flow and covers the damaged area of the vessel, preventing rupture and subsequent stroke.
The experimental rabbits were observed for two weeks after the intervention; the animals remained healthy. According to scientists, this method used in the treatment of aneurysms is also applicable to humans. However, before conducting experiments involving humans, the technology needs to be tested further on animals whose physiology is similar to humans.
