Abstract: In the present study, nanocomposite (ZnO/Cr2O3/NiO) was synthesized by photo irradiation. The synthesized nanoparticles characterized by Scanning Electron Microscopy (SEM), Transmission Electron Microscopy (TEM) and X-Ray Diffraction (XRD). Results show that to nanocomposite (ZnO/Cr2O3/NiO) have average particles size of (ZnO/Cr2O3/NiO) nanocomposite of TEM is (29.6) and SEM is (34.2). The average diameter that obtained from AFM is about 55 nm while the diameter of 60 nm is the lowest diameter and the diameter of 42 nm is the highest percentage in the sample and diameter of the crystal nanoparticles (25 nm) was found (ZnO/Cr2O3/NiO) nanocomposite were applied to study the inhibition of bacterial using Staphylococcus epidermidis (Gram positive), Escherichia coli (Gram negative). The antibacterial activity of (ZnO/Cr2O3/NiO) nanocomposite show a higher inhibition of Escherichia coli bacteria when a compared with Staphylococcus epidermidis also study the effect of nanocomposition (ZnO/Cr2O3/NiO) on the enzyme activity of ALP. The activity of serum ALP in patients with CKD in presence of nanocomposition (ZnO/Cr2O3/NiO) was lower than its activity in this group without nanocomposition (ZnO/Cr2O3/NiO).
