Calcium-based nanowires for bone repair

Abstract Bone defects due to the older population, severe trauma, congenital malformations, resection of bone tumors, and infections are serious problems faced in orthopedic clinical treatment, posing great hazards to human health and life, and external interventions are generally required to promote bone healing. Considering the osteogenic promotion of calcium ions, Ca-POM nanowires were synthesized in this study to facilitate the osteogenesis process through the release of calcium ions. The cytotoxicity test showed that the material possesses good biocompatibility. Furthermore, the Alizarin Red S staining demonstrated that the material could promote osteogenesis, indicating its potential as an ideal candidate for bone repair.
