Green synthesis of spherical silver nanoparticles using Ducrosia anethifolia aqueous extract and its antibacterial activity

Abstract

The present study introduces a simple, cost-efficient, and eco-friendly method for the synthesis of silver nanoparticles (AgNP) using aqueous extract Ducrosia anethifolia and its antibacterial activity. Ducrosia anethifolia aqueous extract was used both as a reducing and capping agent. Synthesized silver nanoparticles were characterized using several techniques including UV-Vis spectroscopy, powder X-ray diffraction (XRD), Transmission electron microscopy (TEM), dynamic light scattering method (DLS), and FT-IR analysis. The results demonstrated that the size range of the synthesized nanoparticles was 4 to 42.13 nm, with the average size of 11.4 nm and in a spherical shape. Moreover, X-ray diffraction analysis indicated that the silver nanoparticles were highly crystalline in nature. Examination of antibacterial activity of synthesized on Gram-positive and Gram-negative bacterial revealed that they had a substantial antibacterial effect. © 2019, Dorma Journals.
