Efficient Route

In the present study, the potential of aqueous extract of Solanum tuberosum for synthesis of Iron Oxide nanoparticles (Fe3O4) was evaluated. An eco-friendly synthesis of iron oxide nanoparticles and characteristics of the obtained Fe3O4 nanoparticles were studied using Ultraviolet-visible spectroscopy (UV-Vis), Fourier Transform Infra-Red Spectroscopy (FTIR), Scanning Electron Microscope (SEM), Energy-dispersive X-ray spectroscopy (EDX), X-Ray Diffraction (XRD) and High Performance Liquid Chromatography (HPLC). The synthesized Iron oxide nanoparticles were effectively utilized for the antibacterial activity and antioxidant studies. The rapid biological synthesis of iron oxide nanoparticles using the extract of S. tuberosum provides an environment friendly, simple and efficient route. From the results, it is suggested that synthesized Iron Oxide could be used effective in future biomedical engineering. Keywords: Antibacterial, Antioxidant, Iron oxide (Fe3O4) nanoparticles, Solanum tuberosum.

Iron Oxide Nanoparticles (IONPs) present unique properties making them one of the most used NPs in the biomedical field. Nevertheless, for many years, growing production and use of IONPs are associated with risks that can affect human and the environment. Thus, it is essential to study the effects of these nanoparticles to better understand their mechanism of action and the molecular perturbations induced in the organism. In the present study, we investigated the toxicological effects of IONPs (γ-Fe2O3) on liver, lung and brain proteomes in Wistar rats. Exposed rats received IONP solution during 7 consecutive days by intranasal instillation at a dose of 10 mg/kg body weight. An iTRAQ-based quantitative proteomics was used to study proteomic variations at the level of the three organs. Using this proteomic approach, we identified 1565; 1135 and 1161 proteins respectively in the brain, liver and lung. Amon them, we quantified 1541; 1125 and 1128 proteins respectively in the brain, liver and lung. Several proteins were dysregulated comparing treated samples to controls, particularly, proteins involved in cytoskeleton remodeling, cellular metabolism, immune system stimulation, inflammation process, response to oxidative stress, angiogenesis, and neurodegenerative diseases.
