Nanoroboti they could be very useful for a variety of things - they can be used to perform operations, examine previously inaccessible places, diagnose diseases in the body, and deliver drugs to a specific place in the body ... What we can not do with microscopic robots from science fiction novels to predict, but their real abilities are already known. In fact, modern nanorobots are not being used due to the absence of the appropriate motors that make them move. Recently, however, scientists have been alerting to flagella bacteria and, after examining them, have suggested an unusual solution to this problem.

Nanoroboti - Physical laws

The laws of physics in the nanoworld are very different from ours, and if we reduced ourselves to the size of a bacterium, one simply could not move in water or any other liquid. However, bacteria do their job well. They use their whips for spiral movement. Earlier, scientists had tried to copy this model of movement and create primitive artificial analogies of the nanoworld, but it had a number of shortcomings - high cost, poor mobility and fragility.

Salmonella Typhimurium

Now, instead of creating flagellates "from scratch," researchers have developed colonies of "Salmonella typhimurium" bacteria. Their flagellates were then covered with silica and nickel so that they could be influenced by the magnetic field. With such a new "engine", bacteria were able to move better than usual. They were able to overcome distances larger than the length of their own body.

Researchers believe that their experiments can help in the development of new areas of medicine. Now a team of scientists is still working on developing the resulting "engines" in the lab. Who knows, maybe using them to create nanorobots to destroy cancerous or other pathological cells.
