    摘要:The present invention provides, in general, compositions comprising a hydrogel and an agent, for example a therapeutic agent or an imaging agent, for locoregional delivery. In certain preferred embodiments of the invention, the hydrogel compositions are detectable by Magnetic Responance and CT Scan and are used for locoregional delivery of therapeutic agents, for example chemotherapeutic agents. The invention also features polymer matrix compositions comprising nanoparticles that can be loaded after polymerization with bioactive agents, for example a diagnostic agent or therapeutic agent.

    摘要:A method for producing a polysaccharide ester microsphere may include forming a polysaccharide ester product from a polysaccharide synthesis, wherein the polysaccharide ester product comprises a polysaccharide ester and a solvent; diluting the polysaccharide ester product, thereby yielding a polysaccharide ester dope; and forming a plurality of polysaccharide ester microspheres from the polysaccharide ester dope. Suitable polysaccharides may include, but are not limited to, starch, cellulose, hemicellulose, algenates, chitosan, and any combination thereof. Esters thereof may be organic esters (e.g., acetate and the like), inorganic esters (e.g., sulfonates and the like), or combinations thereof. Further, the solids conent of the polysaccharide ester dope, in some instances, may be greater than about 16 wt %.
