Scientists have made robots of sperm

German scientists have created the world's first sperm on the remote control. Built-in magnets allow them to manage the process of artificial fertilization of eggs outside or deliver drugs to specific areas of the body.

Researchers at Integrative Nanosciences in Dresden have created the world's first biological robots that are controlled by sperm. They managed to put a single sperm cell into a special metal nanotube, and then manage their traffic with the help of magnets. Biological robots or bioboty can be used for more successful artificial fertilization Or in the treatment of some diseases by delivery of drugs to specific areas of the body.

The length of the magnetic nanotubes is 50 microns, and a thickness of 5 to 8 microns. Scientists put the tube in a liquid that contains the sperm of a bull. In order to capture them, not giving "escape", it had narrow tube at one end. They moved under the influence of a magnetic field, told reporters as the author of the experiment, Professor Oliver Schmidt.

"The most important challenge for us was to create a tube with a diameter slightly larger than the head of the sperm, but to still maintain the mobility of its tail - said Professor Schmidt. - This is the tail moves outside of the tube like a propeller, providing the entire structure with the necessary energy. Of course, It seems the most attractive idea is the use of such robotic sperm for procedures artificial fertilization But our experiments are far from complete. Although I do not see any reason for which this technology would not work as well with human sperm. "(Read More)
