The present disclosure generally relates to biodegradable and bioresorbable materials having a mineral layer on the surface of the material. More particularly, the disclosure relates to biodegradable and bioresorbable orthopedic devices having a degradable mineral layer on the surface thereof that can be used as a delivery vehicle for biological substances. Also provided are various methods of using the mineralized devices in tissue regeneration, including bone tissue engineering, and methods for producing the mineralized devices.

Biologically active sutures for regenerative medicine

A modular peptide design strategy wherein the modular peptide has two functional units separated by a spacer portion is disclosed. More particularly, the design strategy combines a hydroxyapatite-binding portion and a biomolecule-derived portion. The modular peptides have improved non-covalent binding to the surface of the HA-based materials, and are capable of initiating osteogenesis, angiogenesis, and/or osteogenic differentiation.

Methods of decorating hydroxyapatite biomaterials with modular biologically active molecules

A system for growing tissue based upon layers of an inorganic extracellular matrix, wherein each layer of the inorganic matrix is designed to dissolve at a separate rate and result in sequential growth factor delivery upon its dissolution.
