Designing of 3D printed Alginate Di Aldehyde(ADA)-Gelatin(GEL)/ Zinc Doped in Bioactive Glass (ZnBG) scaffolds for Soft Tissue Engineering


Supervisor: Dr. Sara Pourshahrestani, Prof. Aldo R. Boccaccini

Due to an increase in the frequency of trauma and pathological disorders, skin wounds have become a serious healthcare issue. Large trauma wounds lead to severe skin loss and are mainly repaired by scarring. Some wounds can even become chronic needing various treatments and making the healing process expensive [1]. 3D printed hydrogels have emerged as a promising tissue engineering and regeneration platform based on their ability to provide an appropriate environment for cell growth. A suitable hydrogel ink formulation is essential to getting a well-defined scaffold with acceptable post-printing shape fidelity. Alginate has seen tremendous interest in this area due to its biocompatibility, biodegradability, simplicity of functionalization, and quick gelling characteristics [2]. In this project the synthesis and characterization of the physiochemical properties of 3D printed alginate dialdehyde-gelatin (ADA-GEL) hydrogel reinforced by the incorporation of zinc doped bioactive glass nanoparticles scaffolds for soft tissue engineering will be investigated. The project expands from previous research carried out at the FAU Institute of Biomaterials on ADA-GEL hydrogels incorporating inorganic nanoparticles (for example [3]).
