Abstract
A biopolymer solution is polymerized to form a gel which is freeze-dried and crosslinked with ultraviolet radiation to form a biopolymer foam. The foam is filled with a collagen solution and the combination is freeze-dried or the foam is filled with a collagen solution containing extracellular matrix particulates and that combination is freeze-dried, thereby forming a foam to which extracellular matrix particulates are attached.
