ABSTRACT:
Beads having diameters of several tens of micrometers to several millimeters and immobilized with biomolecules are captured by one kind of bead capturing nozzle one by one without fail. Using a bead holding plate having a plurality of wells each of which holds a plurality of the beads and a solution, a vibration generator mounted with a stage to attach the bead holding plate, and a bead capturing nozzle for bead capture connected to a suction pump, only a single bead is captured at the tip of the bead capturing nozzle by inserting the nozzle having an inner diameter smaller than the beads and a negative pressure inside created by the pump into the solution to allow the nozzle to come in contact with the beads in the well, applying a vibration to the bead holding plate by the vibration generator, and withdrawing the bead capturing nozzle into the air.
