Nanotechnology nowadays is gaining increased relevance in scientific research given that nanomaterials have shown improved mechanical, conductive, optical and biofunctional properties. 1 3 In the field of tissue engineering, the development of nanofibrous mats is one of the most promising approaches. The morphological resemblance to the structure of extracellular matrix (ECM) and high surface-area-to-volume ratio make nanofibers very appealing to be used as scaffolds or drug carriers. 4 7
