The German scientists has successfully created a biological robot remote control by magnet works like sperm.
Because this material is a metallic nanotubes ( dark gray ) containing sperm inside the cow . In the future , it may serve the purpose of transporting drugs to conceive or to any place in the body .
Oliver Schmidt - Scientists at the Institute for Integrative Nanosciences in Dresden ( Germany ) , said sperm to create this robot , the scientists used a tube with a diameter of about 0.005 to 0.008 mm and length 0 , 05 mm made from iron and titanium nano . Sperm truth will be contained inside. After that , scientists use magnetic fields to control the direction of metal pipes , lead robot in the direction that they want .
The biggest challenge in making is how to adjust the size of its wider sperm head a bit but still maintain mobility of the sperm tail as well as the ability to trap and prevent sperm exit outside.
"Sperm is an ideal choice because they are harmless to human body, no energy from external support and can swim through mucus," Mr. Oliver said.
Eric Driller at the University of Toronto (Canada) commented: "This approach could pave the way for the use of robotic systems, although the micro-robot to swim as fast as a normal cell biology is very difficult ".
This study is published in the journal Advanced Materials.
