Abstract: A filter apparatus, a method for the manufacture of the filter apparatus, the use of the filter apparatus in medical, chemical and/or biotechnological applications, and an apparatus for use in the manufacture of the filter apparatus. The filter apparatus has a cylindrical housing and a plurality of hollow fibers. The hollow fibers are combined to form a bundle in the housing and are embedded and held in each case at the end sides in a molding compound. The filtrate space is filled with particles of a chemically or physically active substance.

Abstract: A separation material includes a matrix that is bound to a saccharide, enabling the separation from a liquid of substances that selectively bind the saccharide. A method for preparing the separation material and a method for separating substances from a liquid that selectively bind a saccharide of the separation material are also described. A device employs the separation material for separating from a liquid substances that selectively bind to the saccharide of the separation material.

Abstract: A separation material includes a saccharide bound via a linker to a matrix for enabling the separation from a liquid of substances that selectively bind to saccharide moieties. A method for preparing the material, a method for separating from a liquid substances that selective bind to saccharides, and a device including the separation material are also disclosed.

Abstract: An extracorporeal system for liver dialysis comprises a filter device having hollow fibers with integrated ion-exchange particles and hydrophobic adsorbent particles in the filtrate space. The system can be used for the treatment of acute liver failure and acute-on-chronic liver failure.

Abstract: An artificial, extracorporeal system for liver replacement and/or assistance, comprises a liver dialysis device for conducting hemodialysis on a patient suffering from liver failure. The liver dialysis device comprises a first standard hollow fiber membrane dialyzer which does not allow passage of an essential amount of albumin over the membrane wall and which is perfused with the patient's blood, and a second hollow fiber membrane dialyzer which allows the passage of essential but defined amounts of albumin over the membrane wall and which receives the blood of the first standard hemodialyzer. The filtrate space is closed off from the lumen space of the hollow fibers and is populated by adsorbent material which may comprise one or more different adsorbents.

Abstract: Synthetic membranes for the removal, isolation or purification of substances from a liquid. The membranes include at least one hydrophobic polymer and at least one hydrophilic polymer. 5-40 wt.-% of particles having an average particles size of between 0.1 and 15 ?m are entrapped. The membrane has a wall thickness of below 150 ?m. Methods for preparing the membranes in various geometries, and use of the membranes for the adsorption, isolation and/or purification of substances from a liquid are explored.

Abstract: An immobilized enzyme comprises a solid support, an enzyme linked to the solid support and a spacer for coupling the enzyme to the solid support. A method for the production of immobilized enzymes comprises: providing a solid support having amino-functional groups coupled to the support surface; covalently coupling the amino-functional groups with a thermally labile radical initiator; and, contacting the support surface with a solution of polymerizable monomers. The polymerizable monomers comprise functional groups which do not take part in radical polymerization, under conditions where thermally initiated graft copolymerization of the monomers takes place, to form polymer chains on the surface of the support. If the polymer chains do not already comprise primary amino-functional groups, the method further comprises transforming the functional groups in the polymer chains into groups comprising primary amino-functional groups.
