Influence of morphology on the in-vitro bioactivity of hydroxyapatite nanostructures synthesized in the presence of chelating ligands

A novel morphology-controlled synthesis method to fabricate HAP nanostructures is employed by usingdifferent Schiff bases as chelating ligands. The formation mechanism of zero-dimensional (0-D) and one-dimensional(1-D) nanostructures of HAP is also considered. Based on the morphological studies of the final products, it is found thatthe formation of tetradentate and bidentate complexes leads to the preparation of 0-D and 1-D HAP nanocrystals,respectively. The in vitro bioactivity of the as-produced HAP nanostructures is evaluated by soaking the products insimulated body fluid (SBF). The analytical measurements indicate that the changes of the Ca and P concentrations forthe 1-D HAP nanostructures are more than those of the 0-D HAP nanostructures, indicating the good bioactivity of thenanorods and nanobundes
