ABSTRACT:
Disclosed is a wound dressing comprising a therapeutic agent and a matrix comprising polymers joined by cross-linkages, wherein the cross-linkages comprise oligopeptidic sequences which are cleavable by a kallikrein associated with wound fluid such that the rate of release of the therapeutic agent increases in the presence of elevated kallikrein levels.
