Abstract
Development of nano crystalline biomaterials for tissue engineering and biomedical application using different chemical routes and different bio sources has been widely studied in recent years. The objective of this study is to synthesis hydroxyapatite (HAp) biomaterials from fish wastes like fish scale, bones, fins and its comparison with commercial nano HAp powders. Fish scales and bones are chemically treated to wash external protein layers and preserve in dry place. Fish fins are mostly composed of collagen and remaining HAp minerals. After removing collagens, fish wastes are thermally treated to obtain HAp biomaterial. The obtained HAp flakes are milled for about 40-50 hours and comparative characterization studies were performed. Fish waste derived and commercial nano HAp powders are characterized by X-ray diffraction, thermo gravimetric / differential thermal analysis (TG/DTA), size distribution measurement, electron microscopy and Fourier transformed infrared spectroscopy (FTIR). The particle size distribution and scanning electron microscopy confirmed the particle sizes are in the range of 500 nm to 2 µm. Thermal decomposition of fish wastes result in decomposition of organic matters and entrapped water followed by chemical conversion which ultimately forms HAp. Comparative studies of commercial nano HAp and fish waste derived HAp shows significant similarities. This method could be reported as having high reproducibility and conversion of waste materials to biomaterials in an easy, cost effective and eco friendly manner for HAp production.
