Abstract

By applying a single rotary motion to our previously developed magnetic bead-droplet handling mechanism, we newly developed transportation and agitation operation mechanisms aiming at realizing a portable-sized biochemical analysis system. We used two permanent magnets for transporting beads and another magnet coupled with multi-layered flat coils for agitation. They are all mounted on a rotational table, and the total size of the system is 60 times45 times35 mm. We experimentally confirmed that the developed system can do all the beads´ handlings (transportation, extraction, fusion, and agitation) by the rotational motion only.
