There is a significant need for materials that both prevent bacteria adhesion and rapidly form a strong bone-to-implant interface to achieve biomaterial stability. In this way, this project presents the novel poly(lactic acid), gelatin and TiO2 hybrid nanofibres that will be produced via coaxial electrospinning technique. Scanning electron microscopy, transmission electron microscopy, X-ray difractometry, X-ray dispersive spectroscopy and optical spectroscopy will be used to morphological and structural characterization. Bioassays with the nanofibers produced will also be performed. They will succeed in partnership with the Laboratory of Nanomedicine at Northeastern University in Boston, USA. It is expected to obtain PLA/Gelatin/TiO2 hybrid nanofibers in order to obtain bone tissue regeneration. (AU)
