Antibacterial Activity of Silver Nanoparticles Synthesized by Using Extracts of Hedera helix
Journal Title: Zahedan Journal of Research in Medical Sciences - Year 2017, Vol 19, Issue 1
Abstract
Background: Silver nanoparticles (AgNPs) are one of the most widely applicable particles whose application is increasing in Nano world daily. Silver nanoparticles have expressed significant advances owing to wide range of applications in the field of bio-medical, sensors, antimicrobials, catalysts, electronics, optical fibers, agricultural, bio-labeling and the other areas. Green synthesis is the safe and easiest method of producing silver nanoparticles. Because of the production of the silver ions, silver nanoparticles are found to have the antibacterial activity. Objectives: The aim of this study was to investigate antibacterial activity of silver nanoparticles synthesized by using extracts of Hedera helix against Bacillus subtilis and Klebsiella pneumoniae. Methods: In this experimental study AgNPs were prepared by the reaction of 1mM silver nitrate and extracts of Hedera helix. Antibacterial activity of AgNPs was assessed by using disc diffusion method against Bacillus subtilis and Klebsiella pneumoniae. The AgNPs were characterized by UV-visible (vis) spectrophotometer, particle size analyzer by dynamic light scattering (DLS) method, transmission electron microscopy (TEM). Results: AgNPs obtained showed significantly higher antimicrobial activities against B. subtilis and K. pneumonia in comparison to both AgNO3 and raw plant extracts. Conclusions: Biological methods are a good competent for the chemical procedures, which are environment friendly and convenient.
