Abstract
We have studied biohybrid systems integrating artificial components and microorganisms having high functions to improve the functions of microsystems. To increase controllability of such microsystems, we developed a magnetic actuation mechanism using a magnetic structure and an outside magnet. Water-soluble sacrificial layer was patterned by lift-off to release a structure from a substrate. Photoresist mixed with magnetic particles was spin-coated on the sacrificial layer and patterned by photolithography. The structure was assembled in a microfluidic chip. The layer was dissolved in water to release the component. We characterized the actuation of the magnetic structure by magnetizing the component.
