Biodegradable polymers have proved to be useful in versatile applications, including controlled drug delivery,gene delivery, regenerative medicine, and other biomedical applications. Their desirable characteristic features of ample abundance, biocompatibility, and biodegradability make them potential for various uses. Biodegradable polymers are again classified into proteins and polysaccharides. Proteins include Bovine serum albumin, gelatin, lectin, legumin and polysaccharides include chitosan, sodium alginate, dextran, agarose, pollulan and carbapol. The synthetic polymers that can be used are Poly lactic acid (PLA), Ethyl cellulose, Eudragit® S100, Poly lactide coglycolides (PLGA), Poly epsilon caprolactone, Poly ethylene glycol (PEG) and so forth. Biodegradable natural polymers are derived from renewable resources, which mean for example plants, animals and microorganisms, and thus they usually have an excellent biocompatibility and are naturally biodegradable.
