Modulation effects of collagen I on the structure of electrochemically deposited hydroxyapatite coating
- 生命科学－已发表论文 
In this work, collagen I was introduced as an additive to the dilute electrolyte used for direct electrochemical deposition of hydroxyapatite (HA) coating, and its modulation effects on the morphology and crystal structure of the HA coating were examined by SEM and XRD, respectively. Collagen I-modified HA coating was found to exhibit a micro-porous structure. formed by the ordered arrangements of ultra-fine HA crystals. The crystal structure of the modified HA coating was demonstrated to be similar to that of the natural bone. Further compositional studies using FTIR spectroscopy supported the integration of the collagen into the HA coating. (C) 2010 Elsevier B.V. All rights reserved.
