Over the last few years, several studies have been carried out in order to develop new materials for biomedical applications. Material surfaces that provide biomimetic morphology, such as nanoscale architectures, have been shown to alter cell/biomaterial interactions. The electrospinning process has been used for producing polymer fibers due in large part to an increased interest in nanoscale properties and technologies. The use of biocompatible polymers for the viability of cell growth is a promising alternative to improve osseointegration. The purpose of this study is the association of the electrospinning process of biocompatible polymer with TiO2 nanotubes on the Ti30Ta alloy surface. Characterization techniques such as SEM - FEG, X-rays, AFM, TGA, DSC and contact angle will be used for samples analyses. Bone marrow stromal cells (BMSCs) will also be used to investigate the short and long-term cellular response of these biomaterials to cellular adhesion, viability, morphology and proliferation. (AU)
