In this research, we have developed magnetically driven micropumps using microstereolithography. A photopolymer including magnetic nanoparticles was prepared. Both the density of the magnetic nanoparticles and exposure conditions were optimized. It was found that the optimal concentration of magnetic nanoparticles was 15 wt%. The shapes of magnetic rotor models were experimentally examined to drive the rotors in water. By reducing the frictional resistance between the rotor and the substrate, a conical rotor was stably rotated. Finally, a prototype of a micropump using rotor was developed. The optimal condition to drive the micropump was also determined by fluidic analysis using finite element method. The magnetically driven micropumps are useful for micro total analysis systems and medical diagnosis.
