Specialists from the University of Edinburgh (Scotland) have created a new way to treat brain diseases, the university's website reports.
Scientists have discovered a way to treat such diseases without traditional brain surgery. The material states that brain aneurysms are a serious danger - this disease kills about 500,000 people every year. As an alternative to surgery, experts suggested the use of nanorobots.
The nanorobots they created are only 295 nanometers in size, or one-twentieth the size of a human erythrocyte. For comparison: a virus is 100 nanometers in size, most bacteria are 1000 nanometers.
The robots have a magnetic core and their bodies are covered in thrombin, which is used to treat aneurysms. The movement of the nanorobots along the artery is controlled using a magnetic field. At a certain temperature, their shell cracks and the medicine penetrates into the brain. In tests on rabbits, the therapeutic blood clots did not impede overall blood flow to the brain, but instead sealed off weakened areas of blood vessels, the scientists said.

"Nanorobots will open up new horizons in medicine, potentially allowing us to perform surgeries with lower risks than traditional treatments and deliver drugs to hard-to-reach parts of the body with high precision," said Dr Qi Zhou, who participated in the research . |BGNES
