Abstract
An efficient protocol for synthesis of silver nanoparticles (AgNPs) using Xanthium strumerium L. leaves was developed. This study revealed that bioactive compounds present in the extract, function as stabilizing and capping agent for AgNPs. SEM, EDX, TEM and XRD studies confirm the structure, crystalline nature and surface morphology of the AgNPs. Size of synthesized AgNPs was in the range of 20–50 nm having spherical morphology. The AgNPs were found to be toxic against pathogenic bacteria such as Escherichia coli, Pseudomonas aeruginosa and Staphylococcus aureus. The use of AgNPs as antibacterial agent is advantageous over other methods for control of pathogenic microorganisms.Keywords
