Abstract: Greener synthesis of silver nanoparticles (AgNPs) using the leaf extract of Chordia dichotoma. After the addition of leaf extract into the silver nitrate solution the colour change was observed that clearly confirms the formation of AgNPs. The synthesised AgNPs undergo the surface plasmon resonance (SPR) effect for the size reductions were confirmed by the formation of peak at 431 nm from UV-visible spectroscopy (UV-Vis). The stability of the nanoparticles were studied at different time interval (0 to 72 h) using UV-visible spectroscopy and found to be stable. FTIR analysis was performed to identify the active biomolecules that were responsible for the reduction of AgNPs. The synthesised particles were found to be spherical in shape and are in the average size range to nm and were observed to be monodispersed hence it proves that the particles were stable.
