Abstract

The present work deals with the green synthesis of silver nanoparticle from aqueous extract of Pergularia daemia as reducing agent and evaluation of the antimicrobial potential of synthesized green nanoparticles (GNPs). The synthesized silver nanoparticles (SNPs) were characterized by UltravioletVisible absorption spectroscopy (UV-Vis) and high-resonance transmission electron microscopy (TEM) analysis. Visual observation showed that the color of the fresh leaf extracts of P. daemia turned into dark brown after incubation of 24 h with Ag precursors. The TEM analysis showed that nanoparticles were spherical in shape and the size was found to be in the range of 7-22 nm. The green synthesized nanoparticles showed concentration dependent (25 µg/mL, 50 µg/mL and 100 µg/mL) noteworthy antimicrobial activity against E. coli, S. aureus and B. subtilis with ciprofloxacin as a standard. Research findings conclude that GNPs possess superior antimicrobial potential and it is a new option to combat antibiotic resistance.
