Biogenesis of Hematite Nanoparticles Employing Prosopis cineraria and their Antioxidant Property

Abstract

Interaction of green principles and metallic ions is a fascinating field of research to accomplish synthesis of biocompatible nanoparticles. In present study, Fe2O3 nanoparticles were fabricated utilizing phytochemical of wonder tree, Prosopis cineraria a natural herbal infusion. The leaf constituents of P. cineraria acted as reductant and stabilizer. The UV-vis spectrum showed characteristic SPR at 270 nm depicts the formation of iron oxide nanoparticles. Fourier transform infrared (FTIR) spectroscopy suggested that primary carboxylic acid, esters have involved in the synthesis. Further high-resolution transmission electron microscopy (HR-TEM) revealed that the newly formed nanoparticles are square shaped with an average size of 24 nm. Field emission scanning electron microscopic (FESEM) studies depicts their smooth surface without agglomeration. EDAX analysis divulges the elemental composition, Fe, O, Cl, C, K and Ca. The X-ray diffraction (XRD) studies revealed their crystalline phase. Toxicological responses were investigated using in vivo studies with experimental fish Cirrhinus cirrhosus, depicts that the assessed antioxidant enzymes catalase (CAT), glutathione-S-transferase (GST) and superoxide dismutase (SOD) did not show impact and the mortality was recorded only at higher (2200 mg kg-1) concentration.
