Silver nanoparticles (AgNPs) have gained significant attention in recent years due to their remarkable biological properties, including antioxidant activity. In this study, silver nanoparticles were chemically synthesized using 1% trisodium citrate as a reducing agent and 0.01 M silver nitrate solution as a precursor. The synthesis process involved vigorous stirring and heating, resulting in a color change from mild colorless to pale brown, indicating the formation of silver nanoparticles. The obtained nanoparticles were centrifuged, purified, and dried for further analysis. Characterization of the silver nanoparticles was performed using UV-visible spectroscopy, X-ray diffraction (XRD), Thermo Gravimetric Analysis, and Transmission Electron Microscopy (TEM). The antioxidant potential of the synthesized AgNPs was evaluated using standard free radical scavenging assays. The results demonstrated that the chemically synthesized silver nanoparticles exhibit significant antioxidant activity, highlighting their potential application in nanomedicine, food preservation, and biomedical industries. This study provides insights into the synthesis, characterization, and functional properties of silver nanoparticles as promising nano-antioxidants.
