SYNTHESIS, STRUCTURAL, TEXTURAL, OPTICAL, PHOTOLUMINESCENCE AND MAGNETIC PROPERTIES OF HEMATITE (Α-FE2O3) NANOPARTICLES. EVALUATION OF IN-VITRO ANTIOXIDANT AND CYTOTOXICITY ASSAYS

We fabricated Hematite (α-Fe2O3) nanoparticles from thermal decomposition iron(III)malonatedihydrazinate ([Fe2(C3H4O4)3.2N2H4]) inorganic precursor which was prepared by the co-precipitation method and characterized through EDS, ICP-AES, FT-IR and TG-DTA analysis. To characterize the composition, structural phase, chemical state, morphological, textural, optical, photoluminescence and magnetic properties of fabricated Hematite (α-Fe2O3) nanoparticles techniques such as EDS, ICP-AES, XRD, FT-IR, Raman, XPS, SEM, TEM, BET, UV-DRS, PL and VSM were used. In addition, the in-vitro antioxidant activity of Hematite (α-Fe2O3) nanoparticles was assessed by DPPH free radical assay and calculated IC50 value found to be 44.52µg/ml. Also, we found the half maximal Inhibitory Concentration (IC50) value of Hematite (α-Fe2O3) nanoparticles against MCF-7 cell lines (in-vitro) was found to be 97.6652µg/ml
