Micromotorized sperms for artificial fertilization
We present artificially motorized sperm cells—a novel type of hybrid micromotor, where customized microhelices serve as motors for transporting sperm cells with motion deficiencies to help them carry out their natural function. We manage to drive the motorized sperms to an oozyte for potential fertilization and then release it. Despite the fact that there still remain some challenges on the way to achieve successful fertilization, we believe that the potential of this novel approach toward assisted reproduction can be
