Bioactive Biomaterials. Biopolymers now offer product performance, price, environmental compatibility, high visibility and thus far more overall value to the consumer, with far better sustainability for the earth. Based on current findings, electrospinning of biopolymers may be expected to contribute to advanced designs for engineered human skin and to reduction in morbidity from skin wounds. This usually implies that the polymer is made from all identical monomer molecules. This chapter also describes various physical and morphological characterization techniques used for biopolymers.
