Nanotechnology is a new area of research with new possibilities in various fields. Nanotechnology is a having the potential to take forward the agriculture with new tools which promises to increase food production and also protect the agriculture crops from pests, diseases etc. The present study focuses on the green synthesis of silver nanoparticles using plant extracts of Cassytha filiformis. Aqueous silver ions when exposed to plant leaf extract were reduced and resulted in a color change to dark brown indicating the formation of silver nanoparticles by using UV–Vis Spectroscopy which showed peak at in range from 400 nm to 480 nm which are characteristic peaks of silver nanoparticles. Synthesized silver nanoparticles were also characterized by other techniques such as Field Emission Scanning Electron Microscopy (FESEM) showed even shaped spherical nanoparticles with particle size of 42 nm. Energy Dispersive X-Ray (EDX) showed absorption peak approximately at 3 keV. Fourier Transform Infra Red (FTIR) showed chemical interactions of silver nanoparticles and Atomic force microscope (AFM) depicted the three dimensional structure of silver nanoparticle.
