According to the present invention, biopolymers are fixed to a substrate by attaching probe DNA to magnetic beads and fixing the above magnetic beads to the substrate by attracting them using a magnetic attraction. As described above, since magnetic beads with probe DNA attached are fixed to the substrate by attracting them using a magnetic force, the above-mentioned magnetic beads can be fixed with a force stronger than the conventional bonding of probe DNA with the substrate. Accordingly, the magnetic beads are not in danger of exfoliation from the substrate or washing-away of probe DNA during washing treatment.
