Low-cost processing technology for the synthesis of a biocomposite for biomedical applications: A preliminary study

Calcium-phosphate biomaterials,which have a composition similar to bone mineral,represent a potentially interesting synthetic bone graft substitute. in the present study,a biocomposite of calcium phosphate (cap) and collagen (col.) was developed; it's about a triphasic hydroxyapatite/ß-tricalcium phosphate/collagen (hap/ß-tcp/col.). both collagen and calcium phosphate were prepared,for the first time,from the same fish part; moroccan sardine scales (sardina pilchardus). calcium phosphate was isolated by calcination at 1000°c and collagen by extraction with an acid solution. resulting materials were characterized using several analytical tools,including chemical analysis,fourier transform infrared spectroscopy (ft-ir) and x-ray diffraction analysis (xrd). due to its properties,the obtained composite appears to be potential biomaterials for rebuilding small lesionsin maxillofacial surgery,dentistry,aesthetic surgery and particularly in orthopedic surgery. © 2017,university of mohammed premier oujda morocco.
