Biodegradable polymers are polymers which break down after its planned use. Their backbone could possess ester, amide, and ether functional groups. The manner of their degradation as well as their properties is determined by their structure. Biodegradable polymers could be polyesters, polyamides, polyanhydrides, polycarbonates, polysaccharides, etc. Polysaccharides are biodegradable polymers of a kind of monosaccharide or combination of more than one kind of monosaccharide. They are commonly found in living organisms such as plants and animals. The plant origin polysaccharides are such as starch, cellulose, hemicellulose, hyaluronic, alginate, guar gums and etc. and the animal origin polysaccharides are chitin and chondroitin. Polysaccharides play various types of roles in nature. The roles range from food storage, structural support for plants, interphase adhesion in cell wall of plants, structural role for aggrecan assembly and extracellular component, structural support in arthropods, cell wall constituents, a component in plant cell wall and middle lamellar, anionic extracellular cell wall and seed husk. Polysaccharides are mostly considered to be amorphous polymers. Research interests are focused on these green polysaccharides for their abundance renewability, good biocompatibility, non-toxicity, biodegradability, good photo-stability, and capability of enhancing the absorption capacity.
