How useful is SBF in predicting in vivo bone bioactivity
Tadashi Kokubo,Hiroaki Takadama +1 more
TL;DR: Examination of apatite formation on a material in SBF is useful for predicting the in vivo bone bioactivity of a material, and the number of animals used in and the duration of animal experiments can be reduced remarkably by using this method.

The role of prenucleation clusters in surface-induced calcium phosphate crystallization
Archan Dey,Paul H. H. Bomans,Frank A. Müller,Julia Will,P.M. Frederik,Nico A. J. M. Sommerdijk +5 more
TL;DR: It is demonstrated that the surface-induced formation of apatite from simulated body fluid starts with the aggregation of prenucleation clusters leading to the nucleation of ACP before the development of oriented apatITE crystals.

TL;DR: A combination of in situ investigations are presented, which show that for the crystallization of calcium phosphate these nanometre-sized units are in fact calcium triphosphate complexes and demonstrate how the existence of these complexes lowers the energy barrier to nucleation and unites classical and non-classical nucleation theories.
