Bioactive glasses-based scaffolds and polymer fibers containing bioactive glass particles


Supervisors: Marcela Arango-Ospina, Prof. Aldo R. Boccaccini

One aspect of tissue engineering involves the development of highly porous biomaterials, known as scaffolds, that serve to guide the regeneration of new tissues, by supplying a matrix with interconnected porosity and tailored surface chemistry for cell growth [1], [2]. In the last decades, bioactive glasses (BG) have been reported to be suitable materials for tissue regeneration applications, and it has been shown their great osteogenesis capacity [3]. In this study, BG-based scaffolds will be produced with the foam replication technique and 3D printing. The resulting scaffolds will be evaluated for their mechanical and bioactivity properties. On a second phase of this project, the electrospinning technique will be used to produce polymer fibers containing BG particles.
