BIOLOGICAL AFFINITY BASED DELIVERY SYSTEMS

摘要

The present invention provides compositions for drug delivery, comprising a polymer network; a plurality of polysaccharide binding (PB) polypeptides, wherein the plurality of PB polypeptides are covalently bound to the polymer network, but wherein the PB polypeptides do not serve to covalently cross-link the polymer network; and negatively charged polysaccharides non-covalently bound to the plurality of PB polypeptides; as well as methods for making and using the compositions.
