Abstract

See full text

A density gradient biopolymeric matrix implant is disclosed. The implant includes a first homogeneous matrix layer and a second homogeneous matrix layer having a density different from that of the first homogeneous matrix layer. Biopolymeric fibers at the surface of the first homogeneous matrix layer are physically in contact with and cross-linked to the biopolymeric fibers at the surface of the second homogeneous matrix layer. Also disclosed is a three-dimensional density gradient biopolymeric matrix implant that includes a first homogeneous matrix surrounding a second homogeneous matrix having a different density. Biopolymeric fibers at an inner surface of the first homogeneous matrix are physically in contact with and cross-linked to biopolymeric fibers at an outer surface of the second homogeneous matrix. Furthermore, methods for preparing the density gradient biopolymeric matrix implant and the three-dimensional density gradient biopolymeric matrix implant are provided.
