In this study, PEG-Fe3O4/ZnO magetic nanocomposties were synthesized by a ultrasound assistedco-precipitation method. The magnetic nanocomposites were characterized by XRD, FT-IR, FESEMand VSM techniques. The effect of Fe3O4:ZnO ratio on the crystallite size and the lattice parameter ofthe nanoparticles was also studied using XRD. Magetic nanoparticles of PEG-Fe3O4/ZnOnanocomposites exhibit the particles size in the range of 20-30 nm. The VSM measurements at roomtemperature showed that PEG-Fe3O4/ZnO nanocomposites had superparamagnetic properties. Theseresults indicated that ultrasonication time and ration (Fe3O4/ZnO) greatly affect the characteristics ofthe nanoparticles. The antibacterial efficiency of PEG-Fe3O4/ZnO nanoparticles was tested againstSacharomyces cerevisiae, Bacillus subtilis and E. coli bacteria using disc diffusion method.
