摘要： A method for the preparation of a regenerated silk fibroin solution comprises the steps of: treating silk or silk cocoons with an ionic reagent comprising an aqueous solution of monovalent cations and monovalent anions, the cations and anions having ionic radii of at least 1.05 Angstroms and a Jones-Dole B coefficient of between −0.001 and −0.05 at 25° C.; and subsequently degumming the treated silk or silk cocoons; or alternatively, degumming silk or silk cocoons; and subsequently treating the degummed silk or silk cocoons with an ionic reagent comprising an aqueous solution of monovalent cations and monovalent anions, the cations and anions having ionic radii of at least 1.05 Angstroms and a Jones-Dole B coefficient of between −0.001 and −0.05 at 25° C. The invention also extends to fibroin solution, a fibroin material and an implant useful for cartilage repair.

摘要： A method for the preparation of an implantable material for the repair, augmentation or replacement of bone from a fibroin solution, the method comprising the steps of: preparing a gel from the fibroin solution; preparing a material by subjecting the gel to one or more steps of freezing and thawing the gel, wherein the step of preparing the gel from the fibroin solution is performed in the presence of phosphate ions. The material may be treated with calcium ionstoform a fibroin-apatite. A further method comprises the step of treating the material with an isocyanate. The invention also extends to a method for the preparation of an implantable material, wherein a regenerated fibroin solution is used. Also, there is an implantable material and an implant.
