Electro-Magnetic Polyfuran/Fe3O4 Nanocomposite: Synthesis,Characterization, Antioxidant Activity,and Its Application as a Biosensor

Herein, the authors report the synthesis of electro-magnetic polyfuran/Fe₃O₄ nanocomposites using Fe₃O₄ magnetic nanoparticles of different content as nucleation sites via in situ chemical oxidation polymerization method. Surface, structural, morphological, thermal, electrical and magnetic properties of the nanocomposites were studied by FT-IR, UV-visible spectroscopies, XRD, FESEM, TGA, four probe, and VSM, respectively. The effect of Fe₃O₄ nanoparticles content on the electrical conductivity and magnetization of nanocomposites was studied. The obtained polyfuran and polyfuran/Fe₃O₄ nanocomposites were analyzed for their antioxidant activity using 2,2-diphenyl-1-picrylhydrazyl (DPPH) assay. In addition, polyfuran/Fe₃O₄ nanocomposites have been investigated for application as electrochemical biosensor.
