Green synthesis of silver nanoparticles using oak leaf and fruit extracts (Quercus) and its antibacterial activity against plant pathogenic bacteria

Abstract

Silver Nanoparticles as one of Nanotechnology products has extensive medical, industrial and agricultural applications. This paper describes a rapid and eco-friendly method for green synthesis of silver nanoparticles from aqueous solution of silver nitrate using Oak leaf and fruit extracts (Quercus infectoria) in a single-pot process. It was observed that the use of Oak leaf and fruit extracts makes a fast and convenient method for the synthesis of silver nanoparticles and can reduce silver ions into silver nanoparticles within 80 min of reaction time without using any severe conditions. Green synthesis of silver nanoparticles (AgNPs) was characterized by UV-visible (UV–vis) spectroscopy. The UV–vis spectra gave surface Plasmon resonance for synthesized silver nanoparticles peak at 415–445 nm. Further, the AgNPs showed an effective antibacterial activity toward plant pathogenic bacteria.
