Dual functional selenium-substituted hydroxyapatite.
Hydroxyapatite (HA) doped with trace elements has attracted much attention recently owing to its excellent biological functions. Herein, we use a facile co-precipitation method to incorporate selenium into HA by adding sodium selenite during synthesis. The obtained selenium-substituted HA products are needle-like nanoparticles which have size and crystallinity that are similar to those of the ...
متن کاملNovel Patterning of Silicon-Substituted Hydroxyapatite
Template-assisted electrohydrodynamic atomisation (TAEA) spraying of nanometer-sized siliconsubstituted hydroxyapatite (nanoSiHA) was used to pattern implant surfaces for guided cell growth to improve the repair and regeneration of medical implants. A suspension of nanoSiHA was prepared and characterized. Patterns of pillars and tracks of various dimensions were prepared using the suspension. I...
متن کاملSodium-carbonate co-substituted hydroxyapatite ceramics
Powders of sodium-carbonate co-substituted hydroxyapatite, having sodium content in the range of 0.25–1.5 wt.% with a 0.25 wt.% step, were prepared by a precipitation-solid state reaction route. Compacts of the powders were sintered in a CO2 flow (4 mL/min) at 1100 °C for 2 h. The sintered ceramics contained sodium and carbonate ions in the ranges of 0–1.5 wt.% and 1.3–6 wt.%, respectively, whi...
متن کاملCarbonate Hydroxyapatite and Silicon-Substituted Carbonate Hydroxyapatite: Synthesis, Mechanical Properties, and Solubility Evaluations
The present study investigates the chemical composition, solubility, and physical and mechanical properties of carbonate hydroxyapatite (CO3Ap) and silicon-substituted carbonate hydroxyapatite (Si-CO3Ap) which have been prepared by a simple precipitation method. X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), X-ray fluorescence (XRF) spectroscopy, and inductively couple...
متن کاملSurfactant-assisted preparation of fluoride-substituted hydroxyapatite nanorods
Fluoride-substituted hydroxyapatite (FHAp) nanorods have been successfully prepared by adding Tween80. As compared to the spheroidal morphology without any surfactant, the FHAp nanorods prepared with Tween80 were elongated along the c-axis. The reason was attributable to the enlarged difference between the growth rates of crystal surfaces due to the adsorption of Tween80. The effects of the pH ...
