Tissue Engineering and Regenerative Medicine

Poly(lactic acid) (PLA) and poly(glycolic acid) (PGA) have long been popular polymers in the development of tissue engineering scaffolds due to their biocompatibility, bioabsorbability, and good tensile strength. Electrospinning is an attractive approach for the production of non-woven, nano- to micron-scale fibrous tissue engineering scaffolds of complex geometries. In this study, we characterize electrospun blends of PLA and PGA via scanning electron microscopy, tensile testing, differential scanning calorimetry, and phase contrast microscopy to gain a better understanding of these blended structures for potential use in biomedical applications.
