The study investigated the biological synthesis of silver nanoparticles using Murraya koenigii leaf extract and examined how broth concentration affects the reduction mechanism and particle size. Rapid reduction of Ag⁺ ions to 10–25 nm spherical nanoparticles occurs within 15 minutes, XRD confirms an FCC nanocrystalline phase, and higher broth concentrations accelerate reduction and yield smaller particles.
Biological synthesis of silver nanoparticles using Murraya koenigii leaf extract was investigated and the effect of broth concentration in reduction mechanism and particle size is reported. The rapid reduction of silver (Ag + ) ions was monitored using UV-visible spectrophotometry and showed formation of silver nanoparticles within 15 minutes. Transmission electron microscopy (TEM) and atomic force microscopy (AFM) analysis showed that the synthesized silver nanoparticle are varied from 10-25 nm and have the spherical shape. Further, the XRD analysis confirms the nanocrystalline phase of silver with FCC crystal structure. From this study, it was found that the increasing broth concentration increases the rate of reduction and decreases the particle size.
