The present invention relates to methods for preparing porous natural or synthetic material scaffolds with keratin for improving cell affinity.

Biomaterial scaffolds with keratin for tissue engineering

A solute is precipitated from a solution of a solute, a solvent, and a non-solvent by preparing the solution and introducing the solution into a precipitation chamber contain a supercritical fluid.

Method for precipitating a solute from a solution

The present invention relates to a process of making biodegradable and/or bioabsorbable biomaterials and keratin nonwoven fibrous articles by electrospinning fibers from a blend of biomaterials and keratin dissolved in organic solvents includes generating a high voltage electric field between oppositely charged biomaterials and keratin fluid in a syringe with a capillary tip and a metallic collection roller and causing a jet to flow to the roller as solvent evaporates and collecting fibrous membranes or scaffolds on the roller. Keratin increased the cell affinity of biomaterial scaffolds which have potential medical applications.

Biodegradable and bioabsorbable biomaterials and keratin fibrous articles for medical applications

The present invention relates to a method of enhancing the negative ion properties of a material and enhance its moisture management properties if necessary. The method of the present invention teaches the determination of the moisture properties of a material, development of a negative ion agent, and the application of that agent to the material, such steps leading to a material possessing negative ion properties and good moisture management.
