Abstract:
1. A method for manufacturing a bead array, comprising: storing a liquid including a bead in a container, the bead having a biological substance fixed on a surface thereof; ejecting the liquid including the bead to a desired position on a solid-phase base by ink jetting the liquid including the bead; forming a reactive region on the solid-phase base having a cover plate joined to the base surface and a resin film disposed along the periphery of the base surface to form the reactive region within a reactive chamber in which wells join one another through gaps smaller than the diameter of the beads, where the liquid including the bead is ejected; separately storing another liquid including another bead in the container, the another bead of the another liquid having the biological substance fixed on a surface thereof and including an identifier, wherein the identifier is at least one of bead size and bead density; and ejecting the another liquid on the solid-phase base by ink jetting the another liquid.
