Abstract :
Here, we present a method for fabrication of full three-dimensional porous microstructures (microscaffolds) using photocurable polymer. The structures were coated with nickel and titanium for magnetic manipulation and biocompatibility, respectively. Fabricated microstructures were controlled by external magnetic fields for remote actuation. Human embryonic kidney 293 cells were cultured in the microstructures to demonstrate their feasibility for cell transportation. The fabricated microstructures described here are suitable for targeted cell transportation platforms.
