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.

Geometric effects of nano-hole arrays were investigated for label free bio-detection.

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.
