Influence of preparation method on hydroxyapatite porous scaffolds

Preparation of porous hydroxyapatite scaffolds

In this work, the sintering and grain growth of hydroxyapatite green bodies are analyzed in order to identify the optimum heat treatments for the preparation of porous hydroxyapatite scaffolds. Sintering in air at temperatures ranging between 1100 and 1200 °C yields dense materials with narrow grain-size distributions. The scaffolds are formed by the infiltration of polymer foams with hydroxyap...

Preparation and Properties of Modified Hydroxyapatite/Polycaprolacton Composite Scaffolds

In this paper, ultrafine particles of crystalline hydroxyapatite were synthesized by hydrothermal treatment at 180C, and the surface of hydroxyapatite particles was modified by hexametaphosphate for the excellent dispersion properties of HA in the scaffolds. The phase separation was used to fabricate the scaffolds of polycaprolacton/chitosan and hydroxyapatite/polycaprolacton-chitosan. The effe...

Fabrication of Porous Hydroxyapatite-Gelatin Composite Scaffolds for Bone Tissue Engineering

Background: engineering new bone tissue with cells and a synthetic extracellular matrix represents a new approach for the regeneration of mineralized tissues compared with the transplantation of bone (autografts or allografts). Methods: in this study, to mimic the mineral and organic component of natural bone, hydroxapatite (HA) and gelatin (GEL) composite scaffolds were prepared. The raw mater...
