Incorporation of mesoporous bioactive glass particles doped with a phytotherapeutics agent into alginate-based hydrogels for 3D bioprinting

 

Supervisors: Faina Bider, Prof. Aldo R. Boccaccini

Tissue Engineering (TE) represents a method for the repair, regeneration and the replacement of defective tissues [1]. Interconnected 3-dimensional (3D) networks, so called hydrogels, are materials which show promising features for the use as biomaterials in TE [2]. Alginate di-aldehyde (ADA) and gelatin (GEL) are two materials, which are already successfully considered in this field of research [3]. Adding bioactive glasses as inorganic fillers further improves their mechanical as well as biological properties [4]. In addition, the implementation of other bioreactive materials in terms of phytotherapeutics can be used to achieve specific characteristics, such as anti-inflammatory or antibacterial behavior [5]. The aim of this project is to improve the properties of ADA-GEL hydrogels for cell-loaded 3D bioprinting by adding phytotherapeutics loaded mesoporous bioactive glass nano-particles.
