The first sperm based robot

Scientists at the Integrative Nanosciences Research Institute in Dresden, Germany, created the first "sperm-based bio-robot".

This is a control microorganism that is made of metal and sperm of a cow, which can be remotely operated for the purpose of fertilizing an egg or transporting it to any Anywhere within the human body.

This biological robot is made using a micrometer tube of 0.05mm length to hold the sperm, and the tail of the sperm is placed outside. Later, the scientists used magnetic fields to control the direction of the metal tube, leading the robot in the direction they wanted.

"Sperm is an ideal choice because they are harmless to the human body, do not require external support, and can swim through mucus," said lead researcher Oliver Schmidt. It sounds rough, but this is a pretty smart solution.
