Abstract EN
This study reports a facile and ecofriendly approach for the ultrasound assisted synthesis of silver and iron oxide nanoparticles and their enhanced antibacterial and antioxidant activities.
The fenugreek seed extract was used as reducing, capping, and stabilizing agent in the synthesis of nanoparticles.
The transmission electron microscopy results showed that nanoparticles synthesized by ultrasonication have a smaller size (~20 nm) as compared to the nanoparticles fabricated by magnetic stirring (~40 nm).
The color change of the solution from milky white to brown suggested the formation of silver nanoparticles which was confirmed by the presence of an absorbance peak at 396 nm.
The results of powder X-ray diffraction and energy dispersive X-ray spectroscopy confirmed the crystallinity and elements present in nanoparticles synthesized using fenugreek seed extract.
Fourier transform infrared analysis showed that the fenugreek seed phytochemicals were coated on the nanoparticle surface.
Thermal gravimetric analysis showed the thermal degradation and stability of nanoparticles.
Magnetization study of iron oxide nanoparticles confirmed the superparamagnetic nature.
The silver nanoparticles showed antibacterial activities against both gram-negative (Escherichia coli) and gram-positive (Staphylococcus aureus) bacteria, while no antibacterial activities were observed for iron oxide nanoparticles.
The ultrasound assisted nanoparticles showed higher stability and antibacterial and antioxidant activity compared with the nanoparticles fabricated by magnetic stirring.
