Abstract

Nanoparticle is a new innovation of using particles in a new size which ranged from1- 100
nanometers that equal 1 X10-6 meter. In this study we evaluated the antifungal effect of Fe2O3 and
Fe3O4 nanoparticles on Aspergillus flavus (KP137700) selected for the study isolated from broiler
feed by Mycology Department of the Animal Health Research Institute, Giza, Egypt. Fe2O3 and
Fe3O4 nanoparticles synthesized by co-precipitate method. The size of synthesized nanoparticles
was 45 nanometer for Fe2O3 and 9 nanometer for Fe3O4. The antifungal effect Fe2O3 and
Fe3O4 nanoparticles against Aspergillus flavus measured by MIC method and evaluated by scanning
electron microscope. The results revealed that Fe2O3 nanoparticles have antifungal effect more than
Fe3O4 nanoparticles
