“…The starting model used in the Rietveld refinement was based on the structures reported in the literature, reference for hydroxyapatite (American Mineralogist Crystal Structure Database code # 0001257). 15 The background was fitted with an 18-parameter Chebychev polynomial function and the instrumental profile parameters, fitted from the Corundum standard, were kept fixed.…”

In this study, bioactive hydroxyapatite nanoparticles were prepared by two different methods: wet chemical precipitation and biomimetic precipitation. The aim was to evaluate the morphology, particle-size, crystallinity and phases of the powders obtained by traditional wet chemical precipitation and the novel biomimetic precipitation using a supersaturated calcium solution. The nanoparticles were investigated by transmission electron microscopy, Fourier transform infrared spectroscopy and X-ray diffraction. The results revealed that the nanoparticles were formed by hydroxyapatite with a high crystallinity and controlled morphology. Additionally, it was found that the shape and size of the nanoparticles can be modified with each preparation method.

“…Also, preparation of PVA/HA blends has been reported to exploit the advantages of both materials (Kim et al 2008). COL-PVA/HA composite materials have been poorly studied in the literature (Asran et al 2010;Degirmenbasi et al 2006;Kobayashi et al 2004;Poursamar et al 2009). From recently published papers about synthesis of ternary COL-PVA/HA composite materials, a work is the synthesis and the characterization of COL-PVA/HA hybrid materials with 1:2:3 wt compared to COL/PVA hybrid 1:2 wt.…”

Development of bioorganic-inorganic composites has drawn eyes to extensive attention in biomedical fields and tissue engineering. So many attempts to prepare hydroxyapatite (HA), in conjunction with various binders including polyvinyl alcohol (PVA), and collagen has performed for late 20 years. We applied a method based on the phase separation for making of polymer porous membranes. This procedure is induced through the addition of a small quantity of water (polymer-rich phase) to a solution with HA precursors (polymer-poor phase). Thermal and structural composite properties of collagen Hydrolysate (CH)-PVA/HA Polymer-Nano-Porous Membranes were analyzed by Design of experiment that was undertaken using D-optimal approach, to select the optimal combination of nano composites precursor. The resulted composite characters were investigated by Fourier transform infrared, scanning electron microscopy (SEM) and thermal gravimetric analysis. Based on the SEM images, this new method could be clearly concluded to porous CH-PVA/HA hybrid materials. Finally the hemocompatibility of nanocomposite membranes were evaluated by the hemolysis study.

“…2. The m 2 phosphate stretching mode appeared at 465-486 cm -1 and corresponds to PO 4 3-group in FHAp (Degirmenbasi et al 2006). The bands that appeared at 1,042-1,070 cm -1 and 565-567 cm -1 correspond to different modes of the PO 4 3-group in fluorinated hydroxyapatite (Yanbao et al 2008).…”

“…Fluoridated hydroxyapatite (FHAp), where F -partially replaces the OH -in the hydroxyapatite, is considered as an alternative material for bone repair due to its low solubility and good biocompatibility (Boissiere et al 2006;Bose and Saha 2003;Chen et al 2004). Many researchers have also demonstrated that fluoride ions in the culture medium stimulated osteoblastic activities in terms of cell proliferation and differentiation (Chen et al 2007;Choi and Kumta 2006;Darder et al 2006;Degirmenbasi et al 2006). The amount of fluoride ions released from fluoridated hydroxyapatite (FHAp) could be controlled by tailoring the fluoride content in FHAp (Ding et al 2007).…”

Among the composite materials, ceramic/ polymer possesses significant advantages of high mechanical reliability and excellent biocompatibility for applications in load-bearing areas. In this work, PVPCS(Poly (4-vinyl pyridine-co-styrene))/FHAp nanocomposites of varying weight percentages were synthesized and characterized physical-chemically by XRD, FTIR, 31 P NMR, TGA, DTA, and FE-SEM and biologically by antimicrobial and anti-inflammatory assays for evaluating their potential use for biomedical applications. The results indicated that the size and crystallinity of FHAp nanoparticles decrease with increase in PVPCS concentration in the composite. SEM confirmed the presence of FHAp nano rod crystals in PVPCS matrix. The nano PVPCS20/FHAp demonstrated the highest antifungal and antibacterial activity and favorable inhibition of human cell hemolysis. The designed PVPCS/FHAp nanocomposites constitute promising candidates for biomedical applications.
