Hetero-polysaccharide conjugate and methods of making and using the same

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.

Dependencies are inferred from the claim text.
