Abstract:
Silver nanoparticles have received attention due to their physical, chemical, and biological properties and are thus applied in catalysis, nanodevice fabrication, drug delivery and in medicine. Green synthesis of (AgNPs) was achieved by using the leaf and stem aqueous extract <em>Pauzolzia bennettiana</em> and AgNO3. Reduction of silver ions into silver nanoparticles was observed as a result of the color change from pale yellow to dark brown. The synthesized nanoparticles were characterized by UV-VIS and FTIR. UV-Visible spectrophotometer showed absorbance peak at 442nm for AgNps leaf extract and at 428nm for AgNps stem extract. Fourier transform infrared spectroscopy (FTIR) analysis revealed that the functional groups responsible for the stabilization of AgNps. The synthesized silver nanoparticles of aqueous leaf extracts have shown good potential source of antioxidants as compared to silver nanoparticles of aqueous stem extracts.
