Selective protein adsorption property and characterization of nano-crystalline zinc-containing hydroxyapatite

Selective laser sintering fabrication of nano-hydroxyapatite/poly-ε-caprolactone scaffolds for bone tissue engineering applications

“…Miyaji et al 41 reported the application of HA in blood purification due to its selective adsorption. Fujii et al 42 proposed that HA could be used to isolate viral proteins. In these studies, it was generally believed that the complex surface crystal structure of HA and the electrostatic interactions between the adsorbed substances and the HA crystal surface are the main basis for selective adsorption.…”

Rietveld Refinement of the Crystal Structure of Hydroxyapatite Using X-ray Powder Diffraction

“…On the other hand, the CO 3 2-functional group is highlighted by the presence of several vibration bands. The band found at around 875 cm 1 can be characteristic to the ν2 vibration mode and the stretching vibrations of the CO 3 2-group are highlighted by the band in the region 1400 and 1500 cm -1 . The carbonate presence in the specimens is due to absorbance of carbon dioxide from the air during synthesis of the sample and it has been reported by others [23,24].…”

“…The HAp Ca 10 (PO 4 ) 6 (OH) 2 is found in natural human hard tissue and considered as the main inorganic component of bone and teeth [1,2,3]. It has been proven that synthetic hydroxyapatite exhibits properties such as osteoconductivity and osteoinductivity which stimulate bone regeneration [4].…”

Tissue induction, the relationship between biomaterial’s microenvironment and mesenchymal stem cell differentiation

“…growth factors) adsorption on the biomaterial surface and their impact on the MSCs behavior is the key for implants evaluation. Biomaterials might have good biocompatibility as a superior ability for selective protein adsorption, which depending on crystallite size, pore distribution and other structural factors [15]. A protein competitive adsorption process happens after the material implanted into the body, and material surface plays an important role in the protein selective adsorption, which affects cell selective adhesion and directed differentiation of MSCs [16][17].…”
