| 摘要 |
The invention relates to a method for immobilizing nucleic acids on one of the surfaces of a non-porous organic polymeric material which does not carry any primary and/or secondary amine groups. The inventive method comprises the following steps: (a) an aqueous solution containing a nucleic acid as well as a dissolved salt is prepared, whereby the cation of the salt is selected from the group comprised of sodium, magnesium and of mixtures of these cations; (b) the solution mentioned in step (a) is brought into contact with the surface of the polymeric material, and; (c) the surface of the polymeric material, which is in contact with the solution, is irradiated with UV light after step (b) or simultaneously thereto. |
