Biogenic synthesis of antibacterial silver chloride nanoparticles using leaf extracts of Cissus quadrangularis Linn

In this study, we demonstrate a single step method for the synthesis of silver chloride nanoparticles (AgCl-NPs) using leaf extract of Cissus quadrangularis. The AgCl-NPs were characterized by UV–Vis absorption spectroscopy and Fourier transform infra-red spectrum analysis. The crystalline nature and the elemental analysis of the synthesized nanoparticles were analyzed by XRD spectrum, EDAX and HR-TEM. The average size of the AgCl-NPs was found to be 15–23 nm. The antibacterial activity of AgCl-NPs was evaluated against bacterial pathogens of MDR strains by MIC test. Thus, the synthesized AgCl-NPs could be used as an antibacterial agent.

► AgCl-NPs were synthesized using leaf extract of Cissus quadrangularis for the first time.
► Work emphasizes on the chloride ions, present in the leaf extract, is mainly responsible for the synthesis of AgCl-NPs.
► By this biological procedure, spherical shaped AgCl-NPs obtained were similar to previous reports.
► AgCl-NPs were found to have the highest antibacterial activity than reference drug.
