  • Patent number: 11779686
    Abstract: A medical device substrate with a coating including a functional layer located on the substrate, with the functional layer including at least one sugar alcohol and being bonded to the substrate directly or indirectly via a functionalization of the sugar alcohol. Alternatively, the functional layer may also include other saccharides, in which case it is essential that polymerization of the saccharides takes place only upon bonding to the substrate. The inventive medical device exhibits reduced platelet adhesion and aggregation.

  • Publication number: 20150353698
    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.

  • Publication number: 20040188351
    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.

  • Patent number: 6753396
    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.

  • Patent number: 6680204
    Abstract: Reaction of a dialdehyde, particularly phthaldialdehyde (I), with R—Z where Z is a nucleophilic group (preferably SH) and R is polymerisable (e.g. allyl) gives a reactive thioacetal (V) which can react with an amine ligand L—NH2 to produce an isoindole (IV) which may be fluorescent. At some stage, generally before interaction with L—NH2, the R groups are polymerised, possibly leading to self-assembly of the polymer on a metal or SH-bearing surface. Such a coated surface is useful as a transducer in assays or as a binding medium e.g. for chromatography.

  • Patent number: 6670427
    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.
