The field of nanotechnology is the most active area of research in modern materials science. Though there are many chemical as well as physical methods, green synthesis of nanomaterials is the most emerging method of synthesis. We report the synthesis of antibacterial Gold nanoparticles (AuNPs) using flower of medicinal herb, Aerva lanata. The synthesized AuNPs have been characterized by using UV-Vis Spectroscopy, FT-IR Spectroscopy, Transmission Electron Microscopy (TEM) and Cyclic Voltammetry (CV). The mean particle of synthesized NPs was found to be 48.4 nm, as confirmed by TEM. FTIR analysis revealed that the AuNPs were stabilized by proteins, polyphenols, and other aromatic compounds present in the extract. Such AuNPs stabilized by Aerva lanata flower extract were found to have enhanced antimicrobial activity against wellknown pathogenic strains, namely E.Coli, Staphylococus aureus, Bascillus cereus and Pseudomonas aeruginosa
