SUBSTRATE FOR IMMOBILIZING BIOPOLYMER AND METHOD OF IMMOBILIZING BIOPOLYMER BY USING THE SAME

摘要

[PROBLEMS] To immobilize a chain-type biopolymer in an elongated state at a predetermined position on a substrate. [MEANS FOR SOLVING PROBLEMS] A substrate (1) for immobilizing a biopolymer, which has a mask layer (2) provided with multiple through-holes at predetermined positions on a flat active face, is brought into contact with a solution containing a chain-type biopolymer (7). After thus immobilizing the nucleic acid molecule (7) on the active face within a through-hole (3) via physical adsorption or chemical binding, the mask layer (2) is dissolved in a solvent and thus removed while leaving the nucleic acid molecule (7a) alone having been immobilized on the active face within the through-hole (3). Subsequently, the nucleic acid molecule (7a) having been immobilized on the active face is elongated.
