Physical and biological characterization of composite inks containing chitosan for 3D printing

Supervisors: Zoya Hadziehva, Prof. Aldo R. Boccaccini

The primary objective of this scientific research training is to develop and conduct physical and biological characterization of composite inks, which will be used for 3D printing of polymeric scaffolds. The creation of precisely structured biomaterials marks a significant advancement in biomedicine and pharmaceuticals. Due to the high level of control during synthesis, these biomaterials provide an ideal substrate for localized tissue regeneration, drug delivery, and even serve as tissue substitutes. By integrating these materials with bioactive ceramics, an active surface layer promotes interaction with bone tissue. These materials must offer a high degree of structural modification, reproducibility, and cost-effectiveness. 3D printing stands out as an efficient technique for producing three-dimensional biomaterials, providing not only excellent repeatability but also precise control over the material’s structure to meet specific application requirements. The project is part of our collaboration with the group of Dr. Anamarija Rogina from the Faculty of Chemical Engineering and Technology, University of Zagreb, Croatia.
