Abstract
A new gel-like composition of matter containing a complex carbohydrate with a high degree of carboxyl substitution cross-linked by an organic cross-linker has been developed. The cross-linkers have complex ring structures, e.g., polynuclear or heterocyclic compounds, which permit development of two distinct partial positive charges under conditions where a carbohydrate is negatively charged. Antibiotics are the preferred cross-linking agents and a method of sustained release of the antibodies is also disclosed.
