The aim of this study is to investigate the properties of a novel nanocomposite made from whitlockite and nanostructured merwinite. In addition, the effect of merwinite on the apatite formation in this type of composite was evaluated. The nanostructured merwinite was successfully synthesized by the sol gel method. The synthesized merwinite was investigated by XRD and TEM. The nanocompositses were evaluated by SEM, FTIR before and after immersion in SBF. The apatite formation ability of the nanocomposites improved with an increase in the content of merwinite. Furthermore, SaSo-2 cells adhered and spread well on the nanocomposite. The results obtained in this experiment suggest that a whitlockite-merwinite nanocomposite could be a suitable choice for bone tissue engineering.
