Idea of microscopic robots designedfor drug delivery to the depths of living organisms is not new. As a rule, they are able to work even in the most extreme conditions, and can be introduced into the body, even with a conventional syringe. For example, this way you can run nanorobots made by a group of scientists from Cornell University. Each of these robots has a length of 70 microns, which is approximately equal to the thickness of a human hair. To make an army of a million such "creatures", one 10-cm silicon wafer is enough.
To develop a quick method for assembling nanorobotsIt took several years, and now scientists can share very impressive results. The group led by Professor Mark Miskin has already become so accustomed to creating tiny robots that it can produce a million pieces in just a few weeks.
Each robot has four legs, and they canbe made of graphene, platinum and titanium. According to Professor Miskin, the legs are capable of holding a weight 8,000 times greater than their own. It is noteworthy that the thickness of each does not exceed 100 atoms, which also makes a big impression.
As a child, I looked through a microscope and sawcrazy things happen there. Now we are creating something that is also active in such a microscopic size. Now we can not only look at this world, but also be part of it.

At the moment, robots are powered by solarenergy, and therefore can not penetrate into the depths of the body. To remove this restriction and allow them to deliver drugs directly to the foci of disease, the researchers intend to release a version with nutrition from magnetic fields and ultrasound. They also plan to introduce a variety of controllers and sensors.
