Biopolymers fixing substrate and biopolymer fixing method using the same

【Task】 The chain-like biopolymers in predetermined positions on the substrate fixed in a stretched state. A The substrate 1 for biopolymers fixed with a mask layer 2 on a flat active surface having a plurality of through-holes in a predetermined position, by contacting a solution-chain biopolymers 7 are contained, after fixing the nucleic acid molecules 7 on the active surface of the through-hole 3 by physical adsorption or chemical bond, and to dissolve and remove the mask layer 2 in a solvent, is fixed to the active surface of the through hole 3 nucleic acid molecule 7a leaving only, then, to extend the nucleic acid molecule 7a, which is fixed to the active surface. .FIELD 3A
