Scientists developed a sperm-driven micromotor, used as a targeted drug delivery system.
The sperm-hybrid micromotor is appealing to potentially treat diseases in the female reproductive tract.
This system is demonstrated to be an efficient drug delivery vehicle by first loading a motile sperm cell with an anticancer drug (doxorubicin hydrochloride), guiding it magnetically, to an in vitro cultured tumor spheroid, and finally freeing the sperm cell to deliver the drug locally.
