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

摘要

The invention relates to a polymer structure (1) formed by at least a polymer, wherein said structure (1) comprises a volume (2) and a surface (3), 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 (3) into the volume (2) of the polymer structure (1).
