چکیده

Bone scaffolds play an important role in promoting the healing of large bone defects. However, type scaffold material, drug loaded into scaffold, and method preparation have a significant impact on scaffold's properties. In this study, we developed composite comprising sodium alginate (SA), chitosan (CS), hydroxyapatite (HA). The stent carries vascular endothelial growth factor (VEGF), wrapped internal microspheres, vancomycin (VAN). microspheres are outer matrix formed by SA, CS, HA, whereas VAN. Using Fourier-transform infrared spectroscopy (FTIR), X-ray diffraction, scanning electron microscopy analyses, studied contraction rate, swelling, porosity, mechanical properties, degradation, release ability all scaffolds. best as demonstrated results these studies, was HA 6 (SA/CS) 4 @VAN/VEGF scaffold. antibacterial determined using Staphylococcus aureus ( S. ). Cytotoxicity, cell adhesion, osteogenic properties were marrow mesenchymal stem cells. indicate that exhibits good physical, chemical, antibacterial, is, thus, new material with potential.

Synthesis and rheological evaluations of novel injectable sodium alginate/ chitosan-nanostructured hydroxyapatite composite bone pastes

In this paper, nanostructured carbonated hydroxyapatite powder was synthesized using biomimetic method. Physical properties and morphological features of the powder was studied using appropriate techniques such as BET, TEM, XRD and FTIR. The powder was separately mixed with 3 wt. % solutions of either sodium alginate or chitosan to form different pastes. Rheological behavior of the pastes in os...

Synthesis and Characterization of Hydroxyapatite/chitosan Composites

Hydroxyapatite (HAp)/chitosan (CS) composites were synthesized via a one-step coprecipitation method from aqueous solution, with the use of calcium chloride (CaCl2) and disodium hydrogen phosphate (Na2HPO4). CS was obtained via partial deacetylation of chitin with the use of strong sodium hydroxide solution. Composites were prepared with various HAp/CS ratios (30/70, 50/50, 70/30, 85/15) for co...
