Functionalization of oligo(poly(ethylene glycol)fumarate) hydrogels with finely dispersed calcium phosphate nanocrystals for bone-substituting purposes.
TL;DR: In this paper, composite hydrogels consisting of oligo(poly(ethylene glycol)fumarate) (OPF) matrices and CaP dispersions of varying crystallinity were successfully developed using physical or chemical preparation strategies.

Evolution of Amorphous Calcium Phosphate to Hydroxyapatite Probed by Gold Nanoparticles
TL;DR: Amorphous calcium phosphate (ACP) is an important intermediate phase during the biomineralization of apatite as mentioned in this paper. But the detailed mechanism of transformation from ACP to crystallized hydroxyapatite (H...

TL;DR: Crystallization of hydroxyapatite and two tricalcium phosphate polymorphs from the metastable precursor, amorphous calcium phosphate was here studied kinetically and mechanistically using thermal analyses, X-ray diffraction and Fourier-transform infrared spectroscopy.

Confinement Increases the Lifetimes of Hydroxyapatite Precursors
TL;DR: In this paper, the authors employ a model system to study the effects of confinement on hydroxyapatite precipitation from solution under physiological conditions, and find that confinement significantly prolongs the lifetime of metastable phases, here amorphous calcium phosphate (ACP) and octacalcium phosphate (OCP).

TL;DR: The results support the assumption that CaCO3 deposits, acting as bio-seeds for Ca-carbonated phosphate formation, are formed as an intermediate during HA mineralization and that the carbonic anhydrase-mediated formation of those deposits is under a positive–negative feedback control by bone alkaline phosphatase-dependent polyP metabolism, offering new targets for therapy of bone diseases/defects.
