A master's dissertation was discussed in the College of Science, Anbar University on preparing of magnetized graphene oxide nanoparticles with some metals and their use as an antibacterial the student, Mrs. Randa Younis Abdul Jabbar. The dissertation reviewed preparing of graphene oxide nanoparticles via using the Humer method, making superpositions with iron oxide, nickel dioxide and cobalt dioxide with different concentrations, scanning electron microscopy (FESM), X-ray diffraction spectroscopy (XRD) and flame element ratio spectroscopy (FAAS). The dissertation aimed at testing the effectiveness of graphene oxide, inhibiting the growth of bacteria on four types, aureus positive, A. baumannii, K. pneumonia and E. coli negative and using antibiotics (gentamicin, fucidin and amoxicillin) as supporting materials. The dissertation demonstrated evaluating the efficiency of graphene oxide and its compounds in inhibiting bacterial growth.
