A new biohybrid micro‐robot is developed by capturing bovine sperm cells inside magnetic microtubes that use the motile cells as driving force. These micro‐bio‐robots can be remotely controlled by an external magnetic field. The performance of micro‐robots is described in dependence on tube radius, cell penetration, and temperature. The combination of a biological power source and a microdevice is...
A fascinating approach to the development of a hybrid micro‐bio‐robot is presented by Samuel Sanchez, Oliver G. Schmidt and Veronika Magdanz on page 6581. Rolled‐up microtubes are used to capture single sperm cells and remotely control them to a desired location. These microbio‐robots are useful for the controlled guidance of sperm cells, which is a promising feature towards the development of new...
