Bovine serum albumin-modified 3D printed alginate dialdehyde-gelatin scaffolds incorporating inorganic nanoparticles for bone regeneration
Supervisors: Dr. Farnaz Ghorbani, Prof. Aldo R. Boccaccini
Developing multi-material scaffolds that combine 3D printing technology and surface modification is crucial to achieving an efficient bone regeneration process. The objective of this master thesis is to develop bi-layer scaffolds by incorporating polydopamine  and silicate nanoparticle  complexes into 3D printed alginate dialdehyde-gelatin scaffolds , as well as functionalising the surface with a thin layer of bovine serum albumin . Polydopamine and inorganic nanoparticles are expected to synergistically affect the scaffold’s bioactivity and osteogenic performance and improve their mechanical stability. Additionally, surface coating with protein is expected to regulate the system’s thermodynamic behaviour and facilitate tissue-scaffold interaction.
