CROSS-LINKING OF FOAMS OF S-SULFONATED KERATIN

摘要

The present invention relates to a process for cross-linking of highly po rous foams of S- sulfonated keratin, and to highly porous, cross-linked kera tin foams (e.g. scaffolds) as such. Such scaffolds (foams) are particularly useful for wound care applications. Such porous keratin foams can be obtaine d through exchanging the aqueous solution of the reductant as the cross-link ing media with an alcohol solution of the same reductant, and by exchanging the aqueous washing procedures with a similar alcohol washing procedure.
