Video Alert: Scientists Discover Microrobots To Treat Mouse Brain Tumours

The use of neutrophils has proved out to be a promising experiment in the medical field. While it has been successful in treating mouse brain tumours, it still requires a lot of work before it can be used for human patients.

According to a new study report in Science Robotics, scientists have created a microrobot to treat mouse brain tumours. These microscopic robots could navigate through blood near-impenetrable blood-brain barrier to treat the brain tumours in mice. As per the research papers, scientists have created ‘magnetically controlled’ microrobots based on neutrophils, a type of white blood cell. These microrobots will deliver necessary drugs to brain cancer cells.

The researchers at the Harbin Institute of Technology and Harbin Medical University in China were able to combine the natural abilities of neutrophils. These bacteria-fighting blood cells can pass through the blood-brain barrier and yet remain undetected by the immune system. This happens due to the magnetic power that enables the working of these microrobots.

Based on their experimental study, the magnetic particles contain a cancer drug and were coated in E. coli so the neutrophils would consume them. They have named these biohybrids “neutrobots”. Also, the experiment was concluded successfully. It was found that the microrobots were effective in keeping mice alive longer than those that were untreated.

Microrobots have been seen holding an essential potential in the medical field. However, their inability to pass the blood-brain barrier became a major hurdle. As of now, the researchers aim at another detail-oriented study on the same before the human patients can be benefitted from the same.

As mentioned by the researchers, human bodies are much larger than mice and hence the netrobots would be difficult to navigate magnetically. The imaging systems are not that efficient in real time tracking of the neutrobots. But the use of neutrophils has proved out to be a promising experiment.
