    • A method for the isolation of nucleic acids from a liquid sample, which contains nucleic acids, using a filtering device, which has pores, through which the sample is allowed to flow in the course of the isolation, the nucleic acids, and contained in the sample, being retained selectively in or at the pores, wherein the sample is mixed with a concentration of the precipitating agent for nucleic acids, which is sufficient to condense the nucleic acids and the sample is then allowed to flow through the filtering device, the pores of the filtering device used having inner wall regions with variable surface structures, which are constructed differently depending on the medium passed through the pores and by which the permeability of the pores can be adjusted between a state, in which the condensed nucleic acid molecules are retained, and a state, in which the dissolved nucleic acid molecules can pass through.

    • The present invention teaches a novel approach of creating biocmpatible surfaces, said surfaces being capable of functionally interact with biological material. SAid biocompatible surfaces comrise at least two comonents, such as a hydrophobic substratum and a macromolecule of hydrophilic nature, which, in a cooperativity, form together the novel biocoompatible surfaces. The novel approach is ased on contacting said hydrophobic substratum with a laterally patterned monomolecular layer of said hydrophilic and flexible macromolecules, exhibiting a pronounced excluded volume. The htus formed two component surface is, in respect to polarity and morphology, a molecularly heterogeneous surface. Structural features of said macromolecular monolayer (as e.g. the layer thickness or its lateral density) are determined by: i) the structural features of the layer forming macromolecules (as e.g. their MW or their molecular architecture) and ii) the method of creating said monomolecular layer (as e.g. by physi- or chemisorbing, or by chemically binding said macromolecules). The structural features of the layer forming macromolecules(s) is in turn determined by synthesis. AMount and conformation and thus also biological activity of biological material (as e.g. polypeptides) which contact the novel biocompatible surface, is determined and maintained by the cooperative action of the underlying hydrophobic substratum and the macromolecular layer. In this way it becomes possible to maintain and control biological interactions between said contacted polypeptides and other biological compounds as e.g. cells, antibodies and the like. Consequently, the present invention aims to reduce and/or eliminate the deactivation and/or denaturation associated with the contacting of polypeptides and/or other biological material to a hydrophobic substratum surface.
