Title:
SUBSTRATE FOR DISPOSING BEADS AND BEAD DISPOSING METHOD USING THE SAME
Document Type and Number:
WIPO Patent Application WO/2005/093416
Kind Code:
A1
Abstract:
A substrate for disposing beads and a bead disposing method using the substrate enabling the beads capable of efficiently fixing biomolecules to any place in a short time to be stably disposed thereon so that these beads are not peeled off from that place. The substrate (10) for disposing the beads for fixing the magnetic beads (11) in minute reaction chambers (5) comprises a substrate material (1), a magnetic body thin-film (3) disposed on the substrate material (1), and the plurality of minute reaction chambers (5) disposed on the magnetic body thin-film (3). The bead disposing method comprises the steps of disposing a magnet (13) under the substrate (10) for disposing the beads and dripping a dispersion (12), in which the magnetic beads (11) are dispersed, on the substrate (10) to fix the magnetic beads (11) in the minute reaction chambers (5) of the substrate (10) for disposing the beads.
