Green synthesis of silver nanoparticles using latex extract of Thevetia peruviana- a novel approach towards poisonous plant utilization

The development of green synthesis of nanoparticles has received increasing attention due to ease of preparation, less chemical handling, and eco-friendly. In the present study, silver nanoparticles (AgNPs) were successfully synthesized from AgNO3 through a simple green synthesis route using the latex of Thevetia peruviana as reducing as well as capping agent. Synthesized silver nanoparticles were characterized using UV-vis, FTIR, SEM-EDS, XRD and HRTEM. UV-vis spectra showed absorption at 570 nm with shoulder at 395 nm. FTIR spectra analysis confirmed the functional groups involved in the AgNPs formation. X-ray diffraction pattern of AgNPs exhibited the diffraction at 2? = 34.48°, 40.12° and 45.39° corresponding to (222), (400), and (420) Braggs reflection planes of silver nanoparticles. TEM analysis showed the particles size is spherical in nature with its size distribution between 10- 30 nm. The HRTEM image showed 2.59Å interplaner spacing.
