Mesoporous Lanthanum‐Doped Magnesium Phosphate Nanopowders Promote Healing of Critical‐Size Bone Defects: An In Vivo Study

Treating severe bone deformities and abnormalities continues to be a major clinical hurdle, necessitating the adoption of suitable materials that can actively stimulate bone regeneration. Magnesium phosphate (MP) is a material that has the ability to stimulate the growth of bones. The current study involved the synthesis of mesoporous MP and lanthanum (La)-doped nanopowders using a chemical precipitation approach. The nanopowders were analyzed using several techniques, including XRD, FTIR, HR-TEM, BET, XPS, and FE-SEM. The results confirmed the nanopowders' size of less than 40 nm and the successful incorporation of La
