Physicians have welcomed a breakthrough in the medical world in which tiny devices can be used to perform complex tasks Robots will be injected into the human body.
Scientists A team of researchers has developed magnetic nanobots containing blood-clotting drugs encased in a coating designed to melt at the right temperature.
The scientists announced that the technology could ‘open new frontiers in medicine.’
In a study led by the University of Edinburgh’s School of Engineering, researchers said that the use of this technology The mind It can be used to treat bleeding, which causes about 500,000 deaths worldwide each year.
They injected several hundred billion bots into an artery, each about one-twentieth the size of a red blood cell, and then used magnets and medical imaging to guide them to the site of bleeding. Guided from afar.
Once the assembly of tiny bots was in its desired location, the researchers held them together using a magnet and heated them to the melting point of their coatings, thereby placing the drug precisely in place. Where it could stop bleeding or leaks in the brain.
An aneurysm is a blood-filled bulge in an artery in the brain that can rupture and cause fatal bleeding or stroke and disability.
Dr Chi Zhu from the University of Edinburgh’s School of Engineering, who co-led the research, said: ‘Nanorobots are poised to open new frontiers in medicine, potentially allowing us to offer treatments with lower risks than conventional treatments. It will also allow to perform surgical treatment and address problems in hard-to-reach parts of the body with precision.
‘Our research is an important step towards bringing these technologies closer to the treatment of important medical conditions in the clinical setting.’

The researchers said the research shows the nanobots are capable of delivering drugs to specific locations without the risk of them leaking into the bloodstream, which they say is a key test of the technology’s safety and efficacy.
They also say that nanobots could reduce the need for implants, such as coils or stents (mesh tubes), to treat cerebral aneurysms.
This, he said, would reduce the risk of the body rejecting the implants and reduce dependence on blood-clotting drugs, which can cause bleeding and stomach problems. .
It also requires several hours of intensive surgery to implant the aneurysm because of the need to go through the complex network of small blood vessels in the brain, he added.
The same team has also developed nanorobots to remove blood clots, which they say may also show potential in treating strokes.
The research, published in the journal Nanoscience and Nanotechnology, was led by a team from the UK and China.
