The present invention relates to a process for cross-linking of highly porous foams of S- sulfonated keratin, and to highly porous, cross-linked keratin foams (e.g. scaffolds) as such. Such scaffolds (foams) are particularly useful for wound care applications. Such porous keratin foams can be obtained through exchanging the aqueous solution of the reductant as the cross-linking media with an alcohol solution of the same reductant, and by exchanging the aqueous washing procedures with a similar alcohol washing procedure.
La présente invention concerne un procédé pour réticuler des mousses hautement poreuses de kératine S-sulfonée, et des mousses de kératine réticulées, hautement poreuses (par exemple des scaffolds) en tant que tels. De tels scaffolds (mousses) sont particulièrement utiles pour soigner les plaies. De telles mousses de kératine poreuses peuvent être obtenues par en remplaçant la solution aqueuse du réducteur comme milieu de réticulation par une solution alcoolique du même réducteur, et en remplaçant les procédures de lavage aqueux par une procédure similaire de lavage avec un alcool.
