SYNTHESIS AND CHARACTERIZATION OF n-ZnHAp-UPy FOR BONE TISSUE ENGINEERING APPLICATIONS

Supramolecular nanoZnHAp was synthesized by wet chemical technique[1] under specific conditions and the resultingnano-particles were characterized carefully. Zn was doped in the nHAp at a rate of about 3-5 Wt%.The prepared nano- ZnHap-UPy powder was characterized by using Fourier transform infrared spectroscopy and showed the band at 1670cm-1 that is assigned to a urea-C=O vibration. nano-hydroxyapatite, nZnHAp and nZnHAp-UPy were analyzed and confirmed by elemental dispersive X-ray (EDX). The particle size and morphology of the nZnHAp and nZnHApUPy were studied using the scanning electron microscope (SEM) and thermal behavior of the products was examined by thermogravimetric analysis (TGA) and investigated thermal stability of nZnHAp-UPy was decreased down to 300-350C.
