Abstract: A process can be used for preparing a compound A having n groups of formula (I). In Formula (I), X is C2-C12-alkylene or C2-C12-alkylene substituted with C1-C4-alkoxy, C1-C4-alkylthio, and/or interrupted with O or S; R1, R2, and R3 are independently of one another hydrogen or C1-C4-alkyl: and n is an integer of 1, 2, 3, 4, 5, or 6. The process involves reacting a compound B having n —SH groups with a compound C of formula (II), in the presence of a free radical generator.

Abstract: Device for the in-vivo and/or in-vitro enrichment of target structures in a sample liquid, including at least one functional portion, which is provided with receptors for enriching the target structures. In order to improve the enrichment of the target structures in the sample liquid, it is provided according to the invention that the functional portion has a helical shape, which is produced by twisting a symmetrical starting cross section about a twisting axis. The invention likewise discloses a method for producing this device.

Abstract: The invention relates to a process for the production of a structured surface on a polymeric material. In the production process, the polymeric material is brought into contact with a surface-structuring mold which comprises, on a first side, channels of length at least 10 ?m, open toward the first side, and then the removal of the surface-structuring mold from the polymeric material, where the structured surface is obtained on the polymeric material. The polymeric material is brought into contact with the surface-structuring mold at ambient pressure.
