Abstract

The invention relates to a material formed by a polymer substrate and a hydrogel based on vinyl-lactams and ionic methacrylates. The invention also relates to a method for producing this material and to the use thereof for cell culture and cell monolayer engineering, for preparing 3D scaffolds and manufacturing thermosensitive mechanical actuators.

Claims31

Dependent claims

A product comprising:

a) a polymeric substrate and
b) a hydrogel based on vinyl-lactam type monomers, without methacrylates or with ionic methacrylates, and at least two crosslinkers,
wherein there is an interface between the substrate and the hydrogel, an interface formed by a gradient of both, the substrate and the hydrogel network—both forming a semi-interpenetrated network structure—.

Dependencies are inferred from the claim text.
