[PROBLEMS] To provide a method for easily and efficiently immobilizing a biomolecule, for example, a nucleic acid, particularly a short-chain nucleic acid, on a carrier. A solution of a nucleic acid is spotted on a carrier made of a synthetic resin such as polycarbonate, polymethyl methacrylate, acrylonitrile butadiene styrene copolymer, polyethylene, polyethylene terephthalate, polyphenol, polystyrene, polyacrylonitrile, polyvinyl chloride, and aramid. Then, the solution is dried, and ultraviolet rays containing a component having a wavelength of 280 nm are preferably 10 The nucleic acid is fixed to the carrier by irradiating 0 mJ / cm 2 or more. |
