Toxicity Analysis of Hybrid Nanodiamond/Fe3O4 Nanoparticles on Allium cepa L.

Abstract

Materials and methods: The chemicals of hydrochloric acid, nitric acid, FeCl₃.6H₂O, FeCl₂.4H₂O, NaCl, and NaOH (Sigma-Aldrich chemicals, USA) were utilized in this study. A statistical analysis was performed on the results with a prevalence of p < 0.05.

Results: A novel ND/Fe₃O₄ nanocomposite material was successfully synthesized by the in-situ method and characterized by various characterization techniques. The analysis of X-ray diffraction indicated the formation of an ND/Fe₃O₄ nanocomposite with both participating phases. The saturation magnification of the ND/Fe₃O₄ nanocomposite is 13.2 emu/g, whereas for a pure Fe₃O₄ nanomaterial, it is 47 emu/g. The weight rates of ND and Fe₃O₄ existent in the nanocomposite are 28% and 72%, respectively. From the electrical conductivity analysis, ND/Fe₃O₄ exhibits conductivity in the order of 27 times more compared to ND.

Conclusion: The result implies that the product ND/Fe₃O₄ has both magnetic and electrical properties. The biocompatibility of the synthesized ND/Fe₃O₄ material was studied based on the in-vitro method.
