The biological synthesis of nanoparticles using plants or plant derived materials have a significant potential to boost its production without the use of harsh, toxic, and expensive chemicals commonly used in conventional physical and chemical processes. Plant extracts contain bioactive alkaloids, phenolic acids, polyphenols, proteins, sugars, and terpenoids which are believed to first reduce the metallic ions and then stabilize them. Iron oxide nanoparticles have attracted a great deal of attention among researchers because of their multivalent oxidation states, polymorphisms, unique optical, electrical, and magnetic properties and biomedical applications. However, developing a simple, eco-friendly and reliable method for low-dimensional iron oxide nanostructures is still challenging. The bark of cinnamon is one of the most popular spices used worldwide not only for cooking but also in traditional and modern medicines. The most important constituents of cinnamon is cinnamaldehyde which contributes not only to the fragrance but also to its various biological activities. In this work, Iron oxide nanoparticles have been synthesized through a green technique using Cinnamon zeylanicum (cinnamon bark powder) extract. The X-ray powder diffraction measurement shows that the biosynthesized particles are hematite (α-Fe2O3). The microstructure and particle size were investigated using scanning electron microscopy and absorption spectroscopy.
