ABSTRACT

This study aims to synthesize silver nanoparticles using seed extract of Sauropus androgynus as a reducing agent and study their antibacterial activity. For this purpose, silver nanoparticles produced were applied on gram negative bacterial strain Escherichia coli, and gram positive bacterial strain Staphylococcus aureus. The application of the silver nanoparticles on both gram negative bacterial strain E coli, and gram positive bacterial strain S. aureus inhibits the growth of the bacteria. These silver nanoparticles show the same effect on both bacterial strains, although gram negative bacteria have thinner cell wall than gram positive bacteria. This suggests that silver nanoparticles synthesized using seed extract of Sauropus androgynus have a broad spectrum of antibacterial activity.
