چکیده

objective(s): hardystonite (ht) has been successfully prepared by a modified sol-gel method. we hypothesized thatnano-sized (ht) would mimic more efficiently the nanocrystal structure and function of natural bone apatite, owing to the higher surface area, compare to conventional micron-size (ht).materials and methods: the hardystonite nanopowder was prepared via a modified sol-gel method.optimization in calcination temperature and mechanicalball milling resulted in a pure and nano-sized powder which characterized by means of scanning electron microscopy(sem), x-ray diffraction (xrd), transmission electron microscopy (tem) and fourier transform infrared spectroscopy(ft–ir). results: pure (ht) powders were successfully obtained via a simple sol-gel method followed by calcination at1150 °c. mechanical grinding in a ceramic ball mill for 6 hours resulted in (ht) nanoparticles in the range of about 32-55nm.conclusion: our study suggested that nanohardystonite (nht) might be a potential candidate by itself as a nanobioceramic filling powder or in combination with other biomaterials as a composite scaffold in bone tissue regeneration.

Preparation and characterization of hydroxyapatite reinforced with hardystonite as a novel bio-nanocomposite for tissue engineering

Objecttive(s): Despite the poor mechanical properties of hydroxyapatite, its unique biological properties leads we think about study on improving its properties rather than completely replacing it with other biomaterials. Accordingly, in this study we introduced hydroxyapatite reinforced with hardystonite as a novel bio-nanocompositeand evaluate its in-vitro bioactivity with the aim of developi...
