My Master’s research explores Europium-doped calcium silicate (Eu-CS) as a next-generation biomaterial for bone regeneration. Calcium silicate is bioactive and forms hydroxyapatite, but its fast dissolution and limited mechanical strength restrict biomedical use. By incorporating Europium (Eu³⁺), known for its luminescent and functional properties, I investigate how varying Eu concentrations influence the crystallinity, dissolution rate, mechanical strength, and apatite formation of Eu-CS in pellet form. This study provides a foundation for developing multifunctional biomaterials that combine bioactivity, durability, and imaging potential, with future research to expand into cell culture and in vivo studies for clinical translation.
