Boffins create cyborg sperm -

Researchers working at the Institute for Integrative Nanosciences in Dresden, Germany, have created a cybernetic microorganism made of metal and a bull's sperm cell.

Dubbed the "the first sperm-based biobots" the cyber sperm can be remote controlled and used to impregnate an egg or deliver a drug to a target anywhere inside your body.  Of course impregnating an egg might only be useful if you want to give birth to a minotaur.

Sperm based biobots were created using a 50-micron long microtube, which was used to capture the sperm cell, leaving its flagellum outside. The scientists used a magnetic field to control the direction of the metal tube, pointing the sperm were they wanted.

Research leader, Oliver Schmidt said that sperm cells were an “attractive option” because they are harmless to the human body, do not require an external power source, and can swim through viscous liquids.

Other boffins are very excited about the discovery claim that it had been a long time coming.

Eric Diller at the University of Toronto, Canada said that although it is hard to get micro-robots to swim as fast as biological cells this type of hybrid approach could lead the way in making efficient robotic micro-systems.
