Algae robots will treat people

The diagnosis and treatment of anomalies localized in hard-to-reach places is not an easy task. But to help doctors in the near future can come robots, whose size does not exceed the blood cell, reports Zee News. This is a new development of the Chinese University of Hong Kong.

Robots are remotely controlled with high accuracy. They are microscopic algae covered with magnetic nanoparticles. Understand where the robots are located, perhaps during the scan - the algae glow if they are close to the surface of the skin. If the robots are deep in the tissues, an MRI comes to the rescue.

Tests with rats showed: the position of robots can be easily changed using magnets. Robots freely move in the blood, gastric juice and other biological fluids. According to scientists, robots can be used to deliver drugs. Within the framework of laboratory tests, the device isolated drug-active compounds from its center during decomposition.

This allowed selectively to attack cancer cells. In addition, the rate of decomposition of robots is regulated by changing the thickness of the shell. And robots can become a good diagnostic tool that catches abnormal chemical changes inside the body.
