The inventions relates to a method for generating a macroporous hydrogel. In a first step, an aqueous solution of two solutes is produced. The first solute is a polymer that can be cross-linked and is a derivative of polyethylene glycol (PEG) or polyoxazoline (POx) and the second solute is a kosmotropic agent. In a second step, a cross-linking agent is added to the solution. This simultaneously initiates gelation of the polymer and phase-separation, thus creating a macroporous hydrogel. The invention further relates to a macroporous hydrogel, which can be obtained by the inventive method. This macroporous hydrogel is comprised of a cross-linked polymer, which is a derivative of polyethylene glycol (PEG) or polyoxazoline (POx). The hydrogel exhibits interconnected macropores with a size of 200 nm to 1000 μm, particularly 500 nm to 100 μm and is characterized by a pH of of 7,0 to 8,0, particularly approx. 7,4. |
