In Vitro Bioactivity Study on ZnI2-HAp Nanoparticles

Abstract

The manufactured powder of immaculate HAp which is doped with 1.0, 5.0, 10, 20, 30, and 40 in wt.% ZnI2 has been prepared via the sol–gel process. The characterization of samples was achieved by X-ray diffraction (XRD), Fourier Transform Infrared spectroscopy (FT-IR) and Fourier Transform Raman spectroscopy (FT- Raman). The morphology of the obtained HAp powder was studied through SEM analysis. The investigation proves that all prepared samples have the dimension of a nanoscale. The prepared powders were examined for its anti-growth, stimulatory/cytotoxic potentials on normal/activated mouse splenocytes in vitro as well as the lytic effects on red blood cells (RBCs). Results showed that different preparations of ZnI2 had anti-growth effects on normal mouse splenocytes. The pure HAp, 1% and 10% ZnI2 showed no effects on stimulated mouse splenic cells while the other preparations 5%, 20%, 30% and 40% ZnI2 showed inhibitory/cytotoxic effects. All ZnI2 preparations showed safe effects on RBCs.
