Abstract:
Disclosed and claimed are: a composition including at least one glycosaminoglycan, e. g. , CIS, and at least one alginate, e. g. , sodium alginate, wherein:
the at least one glycosaminoglycan and/or the algninate are cross-linked or polymerized, e. g. , the alginate is cross-linked or polymerized, for instance by addition of an inorganic salt, such as a calcium salt; or
the at least one glycosaminoglycan and the alginate are covalently bound, e. g. , by means of a coupling reaction involving a linker molecule such as DVS; or
the at least one glycosaminoglycan and/or the algninate are cross-linked or polymerized, e. g. , the alginate is cross-linked or polymerized, for instance by addition of an inorganic salt, such as a calcium salt, and the at least one glycosaminoglycan and the alginate are covalently bound, e. g. , by means of a coupling reaction involving a linker molecule such as DVS, and the covalent binding can have been performed prior to cross-linking or polymerizing or vice versa; and,
gels comprising the composition; mixtures of such gels or of at least one such gel and at least one such composition; and,
methods for making and using such compositions and gels, including products therefrom such as "paints", sprays, matrices, beads, microcapsules.
