Abstract

In this study, rapid, simple approach was applied for synthesis of metal nanoparticles using Sphagneticola trilobata stem extract. The extract can reduce metal ions into metal nanoparticles within 5 mins after stirring the reaction mixture using magnetic bead stirrer and which was indicated by change in colour of a reaction due to the reduction of metal ions with the help of functional groups in the Plant Extract (BPE), Mel nanoparticles (CuNPs & ZnNPs) were characterized by many techniques like UV-Visible, SEM, FT-IR and XRD. The UV-Vis spectrum of metal nanoparticles revealed a characteristic Surface Plasmon Resonance (SPR) peak at different wavelengths for different metals Scanning Electron Microscopy (SEM) shows spherical shaped and monodispersed nanoparticles with their particular height & length. X-ray spectroscopy (XRD) analysis confirmed the presence of elemental metal particle by showing peak in the metal region. FT-IR analysis confirmed the presence of phytoconstituents in the sample. An effective antimicrobial activity, was seen for the synthesized compounds-against-representative pathogens of bacteria.

Keywords: Sphagneticola trilobata, XRD, UV visible spectroscopy, nanoparticles, Zinc and copper.
