Remotely controllable microrobots are appealing for various biomedical in vivo applications. In particular, in recent years, our group has focused on developing sperm‐microcarriers to assist sperm cells with motion deficiencies or low sperm count (two of the most prominent male infertility problems) to reach the oocyte toward in‐vivo‐assisted fertilization. Different sperm carriers, considering their...
Robotic Microcarriers
In article number 2204257, Oliver G. Schmidt, Mariana Medina‐Sánchez, and co‐workers report the development of 4D‐printed multifunctional sperm‐hybrid microcarriers containing soft and smart materials made with two‐photon lithography. These multifunctional facets enable in situ sperm capacitation/hyperactivation, and the local degradation of the cumulus complex that surrounds...
