Betreuer: Dr. Liliana Liverani, Prof. Aldo R. Boccaccini
Electrospinning is a promising technique for producing fibers ranging from nano- to micrometers which exhibit favorable characteristics, such as high surface area to volume ratio and high porosity, for cell attachment and nutrient diffusion . The morphology of electrospun fibers can be tailored to mimic human extracellular matrix (ECM) for various tissue engineering scaffold applications. Sol-gel method is a technique for producing bioactive glasses incorporating therapeutic metal ions and it can be used in combination with the electrospinning to obtain three-dimensional cotton-like bioactive glass fibers .
Following previous research in our Institute , the aim of this thesis work is the fabrication and characterization of bioactive glass fibers and hybrid fibers obtained by combining electrospinning and sol-gel method. Several compositions of bioactive glasses will be evaluated and several synthetic and natural-derived polymers and their complexes will be investigated for the hybrid fibers.
