Device for capturing beads and method and apparatus for arraying beads

摘要

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.
