 ABSTRACT

The silver nanoparticles were synthesized by biological means using Datura metel leaf extracts prepared at different temperature ranges (00C, 600C and 1000C). Synthesis of silver nanoparticles was confirmed by formation of brown color of reaction mixture and characterized using Calorimeter, Transmission Electron Microscopy (TEM) and Scanning Electron Microscopy (SEM). The diameter of synthesized silver nanoparticles prepared at 600C was found within the range of 18-30 nm. Pseudomonas sp. and Escherichia coli were isolated from soil samples using specific media. Datura metel leaves extracts were used to evaluate their antibacterial effects at two different concentrations (2.5 ml and 4.5 ml) on Pseudomonas sp. and Escherichia Coli. The biggest halo formation was observed at 4.5 ml concentration of the extracts prepared at 600C.

Key words: Antibacterial activity, Datura metel, Silver nanoparticles, SEM, TEM.
