Optimization and fabrication of an anti-inflammatory drug incorporated PCL-based melt electrowriting scaffold for wound healing applications

Supervisors: Dr. Irem Unalan, Prof. Aldo R. Boccaccini

Melt electrowriting is a promising scaffold fabrication technique, characterized by its printing precision, extensive optimization possibilities, and high resolution of 3D printed elements important for tissue engineering applications [1,2]. Polycaprolactone (PCL), a biodegradable polymer, stands out for wound healing applications and is especially well-suited for MEW due to its low melting temperature and fast solidification [3].

This master’s thesis aims to optimize PCL-based MEW derived scaffold in terms of orientation of the polymer fibers to improve its properties and tailor the scaffolds for wound healing applications. Moreover, the incorporation of a biopolymer and an anti-inflammatory drug will be utilized to further improve the chemical and biological properties of the scaffold.
