ABSTRACT

Silver nanoparticles were synthesized using Silver Nitrate as a precursor and leaf extract of Senna Auriculata as a stabilizing and reducing agents. Different concentration of Silver Nanoparticles were prepared from concentrations (1mM, 2mM, and 3mM) with 20 ml of leaf extract. These prepared silver nanoparticles were characterized using UV-Visible, FT-IR, SEM, EDAX and XRD. The possible biochemical mechanism leading to the formation of silver nanoparticles was studied using FTIR. Antibacterial activity of silver nanoparticles were evaluated against Serratia Marcens, Pseudomonas aeruginosa, Staph albus and Bacillus cereus bacteria.

Key words: Senna Auriculata, Ag nanoparticles, Nanomaterial, Green process, Antibacterial.
