title: Metallic nanoparticles augmented the antibacterial potency of Rhodomyrtus tomentosa acetone extract against Escherichia coli.
abstract: The present study was focused on the preparation of gold, silver, and gold-silver-alloy nanoparticles using Rhodomyrtus tomentosa acetone extract (RAE). The synthesized nanoparticles showed the surface plasmon resonance absorption peak corresponding to gold and silver nanoparticle. However, Au-Ag-Alloy nanoparticles showed the single peak between the peaks of AuNPs and AgNPs. TEM observation ascertained the shape and size of nanoparticles. FTIR results indicated the involvement of RAE for the synthesis and capping of nanoparticles. Study on antibacterial activity demonstrated the enhanced activity of RAE capped on silver and Au-Ag-Alloy nanoparticles against Escherichia coli.
