Description
Summary:The role of specific proteins and many other chemicals in the formation of hydroxyapatite crystals has been intensively studied and widely different influences on biomineralization processes in vivo and in vitro have been shown. Chemical phase composition, particle morphologies, and aspects of crystal growth can be affected by the presence of additives. The effect of bisamidinium type dications as tectons on the crystal formation of hydroxyapatite was investigated. Evidence of the structural interactions between three tectons with different numbers and locations of H-bond donor sites and hydroxyapatite crystals has been shown. Some correlations between the molecular structure of the organic tectons and the morphology of hydroxyapatite crystals were observed. These results may be of interest in the control of hydroxyapatite morphogenesis as well as its surface properties.
