Polyhydroxyalkanoates (PHAs) belong to a category of polymers that comprise a group of natural biodegradable polyesters which are synthesized by microorganisms. The vital properties of PHAs such as biodegradability, biocompatibility and non-toxicity make them appropriate for applications as biomaterials. PHAs are used in the field of tissue engineering as bone graft substitutes. They are extensively being used for developing new stents for nerve repair,...
