Silicon-substituted hydroxyapatite nanocomposite: Synthesis, characterization and in vitro bioactivity study in Human Serum Albumin
Nano hydroxyapatite and Silicon-substituted hydroxyapatite nanocomposites with various amount of Si contents (0, 2, 4 and 6 mole % as named as HS0, HS2, HS4 and HS6) were prepared via in situ hybridization method and were analyzed by XRD, FTIR, SEM and AFM techniques. Size distribution of the products demonstrated that hydroxyapatite particles size was between 2 and 53.5 nm with further mean si...
متن کاملbioactivity enhancement of hydroxyapatite by silicon substitution
objective: silicon is an effective element in bone biomineralization; hence si-substituted hydroxyapatite can be a relevant bioceramic as bone materials substitution. materials and methods: stoichiometric hydroxyapatite (ha) and si-substituted hydroxyapatite (si-ha) with different contents of si substitution were synthesized successfully by a hydrothermal method using ca(no3)2, (nh4)3po4 or (n...
متن کاملFacilitated receptor-recognition and enhanced bioactivity of bone morphogenetic protein-2 on magnesium-substituted hydroxyapatite surface
Biomaterial surface functionalized with bone morphogenetic protein-2 (BMP-2) is a promising approach to fabricating successful orthopedic implants/scaffolds. However, the bioactivity of BMP-2 on material surfaces is still far from satisfactory and the mechanism of related protein-surface interaction remains elusive. Based on the most widely used bone-implants/scaffolds material, hydroxyapatite ...
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 کاملHigh Biological performance of Silicon Substituted Nano Hydroxyapatite Synthesized in Simulated Body Fluid at 37°C
In this work, we report high biological performance of silicon substituted nano hydroxyapatite (nHA) prepared by immersion of calcium phosphate and sodium silicate as precursors in Simulated Body Fluid (SBF) solution for 24, 36, 48 and 72 hrs at 37°C. Characterization and chemical analysis of the synthesized powders were performed by Fourier transform, infrared spectroscopy (FT-IR), X-ray powde...
