Comparison Between Green Synthesis and Chemical Synthesis of Silver Nanoparticles: Characterization and Their Antimicrobial Activities

EasyChair Preprint no. 8585

Abstract

This study was conducted on the preparation of novel silver nanoparticles (AgNPs) by using chemical and green approaches. Sodium benzoate (SB) and O-acetylsalicylic acid (AS) are used as capping ligands in the chemical method. While the extract of Teucrium apollinis was used in the green method. Produced AgNPs were stable in room condition up to 3 months. The AgNPs were characterized via using UV-Visible absorption spectroscopy (UV-Vis), dynamic light scattering (DLS), and attenuated Fourier transform infrared (ATR-FTIR). This study confirms the ability of Teucrium apollinis to produce AgNPs with high stability compared with AgNPs stabilized by chemical ligands. The antibacterial activity of AgNPs against Pseudomonas aeruginosa was done as well. The stability of AgNPs were monitored at different pH values (2-12). The use of Teucrium apollinis extract as capping ligand could be good environmentally method to synthesize AgNP that offers a novel and possible alternative to chemically synthesized AgNPs.
