Abstract: A method for producing a plastic article comprising the steps of: (a) loading a surface of a polymeric substrate with an initiator that can be activated thermally or excited by light and which is suitable for generating radicals on the surface of the substrate, (b) loading the substrate, with at least one hydrophobic, polymeric or monomeric grafting reagent capable of polymerization which, as a homopolymer, has a static contact angle with water of at least 75°, measured at 25° C., and which is suitable for reacting with the radicals generated on the surface of the substrate while forming a covalent bond, and (c) exciting or activating the initiator so that the initiator generates radicals on the surface of the substrate and the grafting reagent forms a (three-dimensional) polymer structure that is covalently bonded to the surface of the substrate. A plastic article that can be produced by the method.

Abstract: The invention relates to a membrane module for pervaporation, in particular organophilic pervaporation, having a liquid-tight housing with at least one feed inlet, at least one retentate outlet and at least one permeate outlet that is or can be subjected to a negative pressure or vacuum, wherein a membrane pocket stack is arranged in a housing interior and has a plurality of membrane pockets and seals laid on one another, wherein mechanical pressure is or can be applied to the membrane pockets in the stacking direction by means of a pressure application device for the mutual sealing of the membrane pockets, so that the housing interior is divided up by the membrane pockets into a feed chamber on the outside of the membrane pockets and a permeate chamber in the interior of the membrane pockets. The invention further relates to a use of a membrane module according to the invention.

Abstract: The invention concerns a method for reducing a tendency toward adsorption of molecules or biological cells from solutions or suspensions on a material surface placed in contact with the solution or suspension, as well as a use of the method, and a method for the production of a material with reduced tendency toward adsorption of molecules or biological cells from solutions or suspensions, which is suitable for conducting this method. It is provided that an organic or inorganic support material with a modified surface is used as the material, and that the surface is modified by in-situ polymerization of monomers which are selected as a function of a property of the molecule or the cell, onto the surface.

Abstract: The invention relates to a method for the production of a template-textured material by synthesis of a template-textured polymer (TTP) by performing crosslinking polymerization of functional monomers on a support in the presence of a template, which method is characterized in that a support having a thin polymer layer on the surface thereof is added with a reaction mixture consisting of polymerization initiator, template, functional monomer, crosslinker, solvent and/or buffer and, following sorption of the reaction mixture in the thin polymer layer, the polymerization is initiated and continued until the absorption capacity of the thin polymer layer for the template-textured polymer (TTP) is reached, and the template is optionally removed in a final step, the support used being selected in such a way that it cannot absorb the reaction solution. The materials of the invention are remarkable for their high binding specificity and selectivity for the template.

Abstract: Template-textured materials in the form of template-textured polymers (TGP) on various surfaces including membranes (i.e, template-textured membranes). Such materials are created by modifying the surface of solid carriers, which, by cross-linking polymerization of functional monomers initiated on the surface of said solid carriers in the presence of a template, leads to stable template prints that subsequently bind template molecules or template derivatives in a specific manner. The invention also relates to methods for the production of TGPs and to the use thereof for substance-specific separation of materials.

Abstract: The invention relates to a material for the complex manipulation of nucleic acids as a platform technology for developing integrative, fully automatic systems for nucleic acid analysis. The inventive support material for complex nucleic acid analysis is characterised in that at least one covalently bonded layer is located on the surface, said layer bearing at least two different functional groups which are statistically distributed on the surface. At least one of the functional groups is negatively charged and at least one other functional group is positively charged or chemically reactive or has both of these properties.
