Casuarina equisetifolia Leaf Extract Mediated Biosynthesis of Silver Nanoparticles
K. Muthu*, C. Rathika

In the present work, biosynthesis of silver nanoparticles (Ag NPs) was synthesized from silver ion using the reducing agents of Casuarina equisetifolia L., leaf extract. Initially, the reaction mixture color change has visually identified the product of Ag NPs. The UV-Vis absorbance of the surface plasmon resonance band at 425 nm was confirmed the formation of Ag NPs. FTIR spectroscopy has to identify the presence phytochemical functional group in the extract and capping the NPs. The powdered X-ray diffraction (XRD) analysis of four peaks was identified the fcc crystal nature of synthesized Ag NPs. The surface morphology of the Ag NPs was viewed by High resolution transmission electron microscopic (HRTEM) with selected area electron diffraction (SAED) technique, the spherical shapes of NPs with sizes from 14 to 50 nm.
