Bio Synthesis and Characterisation of Fe3o4 Nanoparticles Using Caricaya Papaya Leaves Extract

Fe3O4 nanoparticles were prepared by using caricaya papaya leaves extract at room temperature. The synthesized nanoparticles were characterised by using UV-Vis absorption spectroscopy, FT-IR, XRD, SEM with EDS techniques. UV-Vis absorption shows a characteristic absorption peak of iron oxide nanoparticles in the range of 190-250 nm. FT-IR measurement was carried out to identify the possible molecules like carbonyl, CH, OH band. From the XRD, it was found that the average particle size of magnetite nanoparticles was found to be 33 nm. SEM shows the plate like structure with coarsened grains and capsule like morphology and EDS showed its chemical composition. This biosynthesis approach is cost effective, eco-friendly and promising for applications in medicine.
