| abstract |
The invention relates to the use of a surface of a plastic based on monomers containing at least one derived from a carboxylic acid structural element (A), wherein the plastic is a poly (meth) acrylate, a polyvinyl ester or a copolymer or mixture thereof with other polymerierbare Substances is for the removal of a linker with a physiologically and / or pharmacologically active substance coupled thereto from a liquid, wherein the linker is selected from (poly) alkylene glycols, (poly) alkyleneimines, (poly) alkyleneamines, (poly) alkylene sulfides and polyoxazolines and at least a structural element (B) which is capable of forming hydrogen bonds, wherein via hydrogen bonds a stable interaction between the structural element (A) of the surface and the structural element (B) of the linker is formed by pH values in the range of 2 to 13 or temperatures up to 60 ° C can not be canceled. |
