Fe-Doping-Induced Magnetism in Nano-Hydroxyapatites.
Iannotti V, et al. Inorg Chem 2017. PMID 28379709
However, especially in the case of iron-doped magnetic hydroxyapatites, it is not clear if the magnetic features come merely from the magnetic phases/ions used as dopants or from complex mechanisms involving interactions at the nanoscale. Here, we report an extensive chemical-physical and magnetic investigation of three hydroxyapatite nanocrystals doped with different iron species and containing small or no amounts of maghemite as a secondary phase. ...

Structural and dielectric properties of yttrium-substituted hydroxyapatites.
Kaygili O, et al. Mater Sci Eng C Mater Biol Appl 2015. PMID 25492204
Hydroxyapatite (HAp) samples doped with 0, 2 and 4 at.% of yttrium (Y) were characterized using X-ray diffraction (XRD), Fourier transform infrared (FTIR) spectroscopy, scanning electron microscopy attached with energy dispersive X-ray (EDX) spectroscopy, antimicrobial activity tests and dielectric studies. ...

Substituted hydroxyapatites for bone repair.
Shepherd JH, et al. J Mater Sci Mater Med 2012. PMID 22389101
Calcium phosphates such as hydroxyapatite have a wide range of applications both in bone grafts and for the coating of metallic implants, largely as a result of their chemical similarity to the mineral component of bone. ...

Synthetic and biological hydroxyapatites: crystal structure questions.
Leventouri T. Biomaterials 2006 - Review. PMID 16519933
Experimental and theoretical studies have demonstrated that biological and synthetic hydroxyapatites display crystal structure similarities and differences that affect greatly the bioactivity of the synthetic materials. Recent developments in structure research of bioapatites report experimental values of the hydroxyl concentration in biological apatites in the range of 20-0% of the amount in synthetic hydroxyapatite. ...

Measurements of the solubilities and dissolution rates of several hydroxyapatites.
Fulmer MT, et al. Biomaterials 2002. PMID 11771695
Therefore, in this study, the solubility and rate of dissolution of three apatite sources, BoneSource, Norian cranial repair system (CRS), and a sintered hydroxyapatite (Calcitite) are evaluated in a thermodynamically closed system. ...The increased solubility of the BoneSource and Norian CRS materials over that of Calcitite is related to their poor crystallinity compared to sintered hydroxyapatite....

Luminomagnetic Eu(3+)- and Dy(3+)-doped hydroxyapatite for multimodal imaging.
Tesch A, et al. Mater Sci Eng C Mater Biol Appl 2017. PMID 28887994
In the present study, luminescent and magnetic hydroxyapatites (HAp) were prepared via doping with europium (Eu(3+)) and dysprosium (Dy(3+)), respectively. ...
