Bioactive glass nanoparticles (BGNs) are emerging biomaterials for a variety of biomedical applications, including soft tissue regeneration [1]. BGNs are used in combination with different polymers to improve the mechanical strength and stability of polymers. The aim of this research project is to enhance the mechanical strength and biological properties of natural hydrogels. BGNs will be incorporated into the hydrogel solution aiming at improving achieving specific interactions between both systems to result in better mechanical properties. BGNs can be used for the incorporation of therapeutics ions such as strontium (Sr) and Lithium (Li) in order to enhance the biological properties of the hydrogel [2,3].
