Molded articles of pure keratin protein, keratin copolymers or crosslinked keratin proteins are produced from a wetted protein powder by application of compression and optionally heat. Stabile materials can be molded or machined.

Biopolymer materials

The invention relates to a material for use as bone void filler comprising soluble keratin protein. The material may be in the form of a putty, gel or emulsion. Additional components may be added to the material to improve handling characteristics and bone enhancement capabilities. The material may be formulated to serve as a suitable carrier for demineralized bone matrix. This invention also describes methods for making the material.

Bone void fillers and methods of making the same

The invention relates to a porous keratin construct material comprising keratin protein for use in wound healing applications. The porous keratin construct is capable of bio-absorbing into a wound to promote wound healing. The rate at which the construct bio-absorbs into the wound may be controlled altered by controlling the degree of disulfide cross-linking between the keratin proteins in the porous keratin construct. The invention is also related to a method of making the porous keratin construct.
