The biological synthesis of nanoparticles using plant extracts plays an important role in the field of nanotechnology. Ferric chloride hexa hydrate and Ferrous chloride tetra hydrate has been used as metal precursors. The phytochemicals present in the Datura inoxia leaf extracts act as a reducing as well as stabilizing agents, which include flavonoids, phenolic compounds, cardiac glycosides and sugars. The formation of the Fe3O4 nanoparticles was first monitored using UV-Vis absorption spectroscopy. The UV-Vis spectroscopy revealed the formation of Fe3O4 nanoparticles by exhibiting the typical surface plasmon absorption maxima at 270-290 nm. The colloidal solutions were dried in petri-dish to analyze the samples. The dried form of synthesized nanoparticles was further characterized using Fourier transform infrared (FTIR) spectroscopy.
