ABSTRACT

The present study deals with a cost effective and eco-friendly approach for green synthesis of silver nanoparticles (Ag NPs) using seed aqueous extract of Zizyphus jujuba as capping and stabilizing agent. Observations of nanoparticles under UV-visible spectrophotometer were promising and rapid production of surface plasmon resonance was observed at 426 nm. XRD pattern suggests the formation of crystalline particles with face centered cubic (fcc) structure. FTIR spectroscopy peak at 1384.1 cm−1 corresponds to C-N stretching of aromatic amine group. SEM showed spherical, aggregated shaped NPs with an average size of 42.1nm. EDAX analysis confirmed the presence of elemental metal signal. AFM analysis showed the irregular surface morphology and the presence of both individual and agglomerated nanoparticles. Anti-termitic activity was investigated using varying concentrations of aqueous seed extract of Z. jujuba, AgNO3 solution and synthesized Ag NPs by no-choice bioassay test for 24 h. In the present study, the efficacy of the aqueous seed extract of Z. jujuba and green synthesis of Ag NPs is a simple, cost-effective and eco-friendly approach to control the C. formosanus.
