A palmtop-sized rotary-drive-type biochemical analysis system by magnetic bead handling

By applying a single rotary motion to our previously developed magnetic bead droplet handling mechanism, we recently 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 × 45 × 35 mm3. We experimentally confirmed that the developed system can do all the bead handlings (transportation, extraction, fusion and agitation) by rotational motion only.
