Abstract
Biomaterials are disclosed having unique properties that make it a useful material in adhesives, local drug delivery applications and as filler or bulking material. The biomaterials are strong, safe and easily used as a surgical adhesive. Treated chitosan, modified chitosan or modified and treated chitosan compositions are disclosed displaying strengths suitable for general surgical applications. The materials can be used as a drug delivery vehicle which allows for the localization of the delivered drug as well as a programmable tether which allows for the release of the drug on a timed basis or in response to a physiological state such as the release of proteolytic enzymes. The materials of this invention can also be modified and treated to optimize the retention of water, thereby serving as a useful filler or bulking material.
