In recent years polymer science has been developed enormously. Researchers have made some significant discoveries and advancements in this field. All these things have lead to a new era of polymer science especially biodegradable polymers. Today a number of biopolymers are known and used for different purposes in biomedical applications. Biodegradable polymers have played a significant role in therapeutics and drug delivery. These biopolymers are advantageous in tissue engineering and other drug delivery systems. A number of biopolymers and their blends are available in market with various physical, chemical and biological properties. The suitability of polymer for biomedical applications depends on its biocompatibility, degradation process (metabolites) and non-immunogenic property. This review summarizes different polymers, their physiological characters, and their use in biomedical applications along with the compilation of recent patents related to biodegradable polymers.
