Magnetically manipulated microrobots are demonstrated by H. Choi, B. J. Nelson and co‐workers on page 5863 for targeted multi‐cell transportation. Fully 3D porous structures are fabricated with a photocurable polymer using a 3D laser lithography system. The structures are coated with nickel for magnetic actuation, and with titanium to ensure biocompatibility for possible in vivo applications. The fabricated microrobots are controlled in the fluid by external magnetic fields. Multiple cells are cultivated in the microrobot to show the possibility for targeted cell transportation.
