Drug loaded mesoporous bioactive glass nanoparticles for wound healing applications


Supervisor: Prof. Aldo R. Boccaccini

In the past years mesoporous bioactive glass nanoparticles (MBGNs) have gained a lot of popularity as multifunctional platforms not only for bone tissue engineering [1], but also for soft tissue applications [2]. When it comes to wound healing, the presence of different ions in the MBGNs’ structure leads to several therapeutic effects (hemostatic, antibacterial, angiogenesis, etc.), specifically targeting the regeneration process [3]. At the same time, the unique textural properties of the MBGNs could assure a high drug loading efficiency and a controlled release of active compounds over long periods of time [4], [5]. Thus, one of the aims of this study is to develop and characterise MBGNs loaded with phytoterapeutic agents. These particles will be further incorporated in a hydrogel with the purpose of obtaining composite scaffolds with enhanced properties for skin regeneration.
