Abstract
An interpenetrating polymer network (IPN) structured hydrogel includes a crosslinked first natural polymer macromer with a first elasticity and an interpenetrating network of crosslinked second natural polymer macromers having a second elasticity higher than the first elasticity, the IPN structured hydrogel being cytocompatible, and, upon degradation, produce substantially non-toxic products.
