Magnetically manipulated microrobots are demonstrated for targeted cell transportation. Full three‐dimensional (3D) porous structures are fabricated with an SU‐8 photoresist using a 3D laser lithography system. Nickel and titanium are deposited as a magnetic material and biocompatible material, respectively. The fabricated microrobots are controlled in the fluid by external magnetic fields. Human embryonic kidney 239 (HEK 239) cells are cultivated in the microrobot to show the possibility for targeted cell transportation.
