Background: Recently, the nanoparticle (NP) application in many fields of medicine due to their specific physical and chemical properties has been developed. Therefore, especially in vivo evaluation of their toxicity is necessary. The aim of this study was to compare the toxicity of Fe3O4NPs coated with biocompatible compounds and uncoated NPs. Methods: Wetted chemical method (or wet chemical method) was used to synthesize Fe3O4NPs. The synthesized NPs were coated with chitosan and the coating interactions were investigated by Fourier-transform infrared spectroscopy. The magnetic and structural properties of Fe3O4and coated Fe3O4NPs were evaluated by transmission electron microscope and X-ray diffraction. The toxicity assessment of Fe3O4and coated Fe3O4NPs was studied in mice by intraperitoneal injections during the 1-month period. Antioxidant enzyme glutathione peroxidase (GPX), malondialdehyde, and low-density lipoprotein/high-density lipoprotein were measured 15 and 30 days after injection. Results: The synthesized NPs have a single phase and spinal structure and their size distribution in the net form is 5–10 nm. Some factors were changed due to the injection of both uncoated and coated NPs. The all-used concentration of chitosan-coated Fe3O4NPs could increase the GPX enzyme activity. The Fe3O4NPs can reduce the GPX enzyme activity in high concentration (50 mg/kg, 100 mg/kg, and 150 mg/kg). Conclusion: The results indicated that NPs based on their dosage and body condition can induce toxicity effects in the body. It should be mentioned that the chitosan-coated ones can decrease their effects.
