Semisynthetic beta-lactam antibiotics are among the most used pharmaceuticals. Their use in veterinary and human medicine is in continuous expansion. There is a growing need for developing bioactive i...
Chemical Synthesis, Characterization, and Biocompatibility Study of Hydroxyapatite/Chitosan Phosphate Nanocomposite for Bone Tissue Engineering Applications
Chemical Synthesis Biocompatibility Hydroxyapatite/Chitosan Phosphate Nanocomposite Bone Tissue Engineering Applications
2009/9/2
A novel bioanalogue hydroxyapatite (HAp)/chitosan phosphate (CSP) nanocomposite has been synthesized by a solution-based chemical methodology with varying HAp contents from 10 to 60% (w/w). The interf...
Influence of Preparation Factors on Ca/P Ratio and Surface Basicity of Hydroxyapatite Catalyst
Hydroxyapatite Calcium/phosphorus ratio Basicity Basic site density
2009/8/4
We aimed at precision control of the basicity of hydroxyapatite (Ca10(PO4)6(OH)2; HAP) and paid attention to four key factors in the synthesizing process—the solution's Ca/P ratio, pH, temperature and...

Porous hydroxyapatite and biphasic calcium phosphate ceramics promote ectopic osteoblast differentiation from mesenchymal stem cells
calcium phosphate ceramics porous structure osteogenesis
2010/1/19
Because calcium phosphate (Ca–P) ceramics have been used as bone substitutes, it is necessary to investigate what effects the ceramics have on osteoblast maturation. We prepared three types of Ca–P ce...
