Introduction: An ideal bone repair scaffold should have dual functions of osteoinductive ability and in vivo imaging. In this study. the simultaneous substitution of silicon (Si) and gadolinium (Gd) in hydroxyapatite (HA) as potential multifunctional bone graft materials has been successfully developed. Methods: A series of HA nanoparticles (HA NPs) doped with different proportions of... https://parisnaturalfoodes.shop/product-category/rose-soap/
