Characterization and <i>In Vitro</i> Antioxidative Potential of Silver Nanoparticles Biosynthesized From <i>Annona muricata</i> Bark

This study introduces a highly effective technique for producing silver nanoparticles (AgNPs) utilizing an extract from the bark of Annona muricata, which is rich in bioactive compounds. The AgNP synthesis was performed at room temperature, providing an environment-friendly and cost-effective alternative to traditional methods that involve harmful chemicals and high energy consumption. Characterization of the AgNPs was performed using various techniques: scanning electron microscope and transmission electron microscope analyses revealed spherical nanoparticles ranging from 29[Formula: see text]nm to 67[Formula: see text]nm in size, FTIR techniques was used to analyze the functional groups involved in the reduction and stabilization, UV-Vis spectroscopy confirmed surface plasmon resonance peaks, X-ray diffraction analysis indicated a face-centered cubic crystal structure and energy-dispersive X-ray (EDAX) analysis verified the elemental composition and stabilization. The antioxidant properties of biogenic AgNPs were evaluated using in vitro assays, which demonstrated their significant antioxidant efficacy. This study highlights the potential of A. muricata bark extract as a sustainable and effective agent for decreasing and stabilizing the synthesis of AgNPs. This technique demonstrates promising potential as antioxidant therapy.
