3-D printed hierarchical polymer-bioactive glass composites incorporating biologically active agents as a new family of scaffolds for bone tissue engineering


Betreuer: Prof. Aldo R. Boccaccini

Bone tissue engineering usually requires the development of suitable scaffolds which should be nontoxic, bioactive and mechanically competent. In this context, bioactive glass (BG)-based scaffolds that are structurally as well as biochemically compatible with natural bone (osteogenic, angiogenic) are being continuously developed since the first 3D Bioglass scaffolds developed in 2006 [1]. This project investigates the development of a new family of bioactive glass based scaffolds which should exhibit controllable pore architecture, excellent mechanical and biological properties and tailored degradability. A convenient alternative to develop such improved scaffolds for bone regeneration is the combination of BG and a biopolymer forming a composite [2] and the use of additive manufacturing methods. In this project scaffolds based on bioactive glass and PLA/PCL will be fabricated by Fused Deposition Modelling (FDM), as introduced recently [3]. The biological properties of these scaffolds will be significantly improved by incorporating biologically active agents, for example as a tailored coating of the scaffold struts by mesoporous (BG)/biomolecule layers.
