This paper discusses the dependence of microstructure and mechanical properties of sintered biphasic calcium phosphate (BCP) on sintering temperature and compacting pressure of BCP dense bodies. BCP nanopowders were prepared via hydrothermal method using eggshell as the calcium source, followed by compaction into circular disc shape at various pressure and

Here we present magnesiumdoped biphasic calcium phosphate (MgBCP) using chemical doping process through a solgel method. MgBCP was produced using calcium nitrate tetrydrate and diammonium hydrogen phosphate as the precursors for calcium and phosphorus, respectively. Magnesium nitrate was used as the source of the dopant.

In the present study, we established chitosan/biphasic calcium phosphate (CS/BCP) scaffolds functionalized with ArgGlyAsp (RGD) and BMP2loaded nanoparticles. The resulting scaffolds were highly similar to natural bone extracellular matrix (ECM) in terms of composition and structural properties. First, we synthesized CS/BCP composite bionic scaffolds via the freeze

Magnesiumdoped biphasic calcium phosphate nanopowders via solgel method IIUM Repository (IRep) Biphasic calcium phosphate (BCP) is a mixture of nonresorbable hydroxyapatite (HA) and the resorbable tricalcium phosphate (TCP) is an interesting material for bone implant as it shows biocompatibility and bioactivity to tissue bone.
The present research describes synthesis of hydroxyapatite (HAp) nanopowders using a sol–gel route with calcium nitrate and ammonium hydrogen phosphate as calcium and phosphorous precursors, respectively. Sucrose is used as template material, and alumina is added as a dopant to study its effects on particle size and surface area. Synthesized powders are characterized using X‐ray

Magnesium–calcium phosphate cement (MCPC) has been reported as a promising candidate for bone repair with promoted osteogenesis both in vitro and in vivo. However, relatively little is known about the effects of MCPC on immune response and the following outcome. In this study, we investigated the interactions between macrophages and MCPC. Here we found that the
