Abstract
This study presents a straightforward, green, and
efficient method for synthesizing silver nanoparticles (Ag-NPs) using Jatropha
leaf aqueous extract used as a reducing agent. The synthesized Ag-NPs displayed
a distinct surface plasmon resonance (SPR) peak at 435 nm. Fourier Transform
Infrared Spectroscopy (FTIR) analysis identified the functional groups involved
in stabilizing and Jatropha encapsulating the Ag-NPs. Dynamic Light
Scattering (DLS) measurements revealed a particle size distribution of 16 ± 2 nm.
Additional characterization was conducted using X-Ray Diffraction (XRD),
Scanning Electron Microscopy (SEM), and Transmission Electron Microscopy (TEM).
The Jatropha encapsulated Ag-NPs exhibited significant antibacterial
activity against Escherichia coli and Bacillus subtilis and detection of metal
ions.
