A PROCESS FOR RAPID BIOSYNTHESIS OF SILVER NANOPARTICLES USING SEED EXTRACT OF SYZYGIUM CUMINI A MEDICINAL PLANT

摘要

The present invention provides a rapid and ecofriendly method of making silver nanoparticle using aqueous extract of syzygium cumini seeds. The method involves preparation of aqueous extract from fine seed powder of syzygium cumini, boiled for 5 min at 100�C, centrifuged and filtered through Whatman filter paper No. 1, The filtrate is used for bio-reduction of metal salts to synthesis metal nanoparticles. In another important aspect of the invention provides method for bioreduction of AgN03. The bio-reduction of AgN03 using SCSE is carried out at temperature range from 4 to 50�C and salt concentrations varying from 0.1 to 5 mM. In another very important aspect of the invention nanoparticles are characterized using UV-Visible spectroscopy (UV-Vis), transmission electron microscopy (TEM), energy dispersive spectroscopy (EDS), X-ray diffraction (XRD), dynamic light scattering (DLS) and cyclic voltametry (CV).
