The invention relates to a polymer structure () formed by at least a polymer, wherein said structure () comprises a volume () and a surface (), wherein said polymer comprises a plurality of polymer chains connected by linkings, characterized by a linking density, wherein said linking density increases, particularly monotonously, from the surface () into the volume () of the polymer structure ().

Electrochemically engineered surface of hydrogels, particularly peg hydrogels, for enhanced cellular penetration

The invention relates to a method, a device and a system for producing particularly a hydrogel () and for controlling an enzymatically catalyzed formation of a covalent bond in a solution, wherein said covalent bond is formed between a first compound () comprising a first moiety () and a second compound () comprising a second moiety (), wherein the first and the second moiety () are a substrate of an enzyme wherein said enzyme catalyzes the formation of a covalent bond between the first and the second moiety (), and wherein a voltage is applied to the solution for spatially controlling said formation, wherein said voltage is adjusted such that it induces electrolysis of said solution.
