Portable rotary-drive-type biochemical-analysis system based on magnetic bead-droplet handling

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.
