Green Synthesis of Silver Nanoparticles Using Flos Sophorae immaturus Extract and Bactericidal Activity

Abstract:

Article Preview

Silver nanoparticles (AgNPs) were rapidly synthesized by treating silver ions with the extract of a well-known Traditional Chinese Medicine herb, Flos Sophorae Immaturus, at room temperature. The AgNPs were characterized by UV–vis spectroscopy and zeta potentials analysis. The bactericidal activity of the AgNPs against S. aureus and E. coli was investigated. The results indicated that the AgNPs synthesized by Flos Sophorae Immaturus extract were water-soluble nanoparticles with 30-60 nm size, zeta potential studies showed that the surface charge of the formed nanoparticles was highly negative, and the antibacterial activity of the green prepared AgNPs exhibited potent bactericidal activity on S. aureus and E. coli.
