Abstract
Covalent compositions of N,O-carboxymethyl chitosan (NOCC) are disclosed. NOCC can be intra- or intermolecularly linked, either through a direct bond or through a bridging moiety. Also disclosed are methods for preparing and using the covalent NOCC compositions. The NOCC compositions are useful in the administration of therapeutically active compounds and for wound management.
