Antioxidant, anti-cancer, and DNA cleavage activities were based on standard&lt;em&gt; in vitro &lt;/em&gt;bioassay methods. &lt;strong&gt;Results: &lt;/strong&gt;The UV-vis absorption peak at 430 nm suggests the formation of silver-based NPs. The FESEM imaging showed spherical-to-cubical shaped MY-Ag NPs with an average size of 45.35 nm. The EDX analysis showed the presence of elemental Ag (89.40%) and N (10.22%), suggesting a successful synthesis. The XRD analysis revealed various peaks at 38.37⁰, 43.56⁰, 63.76⁰, and 77.77⁰, which suggest metallic silver reflections, further establishing the crystallinity of NPs. The MY-Ag NPs inhibited O&lt;sub&gt;2&lt;/sub&gt; -, OH-, H&lt;sub&gt;2&lt;/sub&gt;O&lt;sub&gt;2&lt;/sub&gt;, and NO free radicals in a dose-dependent manner. At 50 and 80 μg/mL, it demonstrated a better inhibitory effect on OH- radical than &lt;em&gt;L&lt;/em&gt;-ascorbic acid. The cytotoxicity (IC&lt;sub&gt;50&lt;/sub&gt;) against human cancer cell lines of the kidney (ACHN) and the liver (HepG2) were 54.21 ± 0.06 μg/mL and 33.36 ± 2.25 μg/mL respectively at 48 h post-treatment. Lastly, at 20 mg/mL for 120 minutes, MY-Ag NPs cleaved DNA, acting as chemical nucleases. This may suggest its capacity to impede cancer cells by cleaving the genome. &lt;strong&gt;Conclusion: &lt;/strong&gt;Therefore, this study has shown that Myricitrinbased Ag NPs possess notable antioxidant and cytotoxicity that can be further exploited in the search for newer anticancer agents.&lt;/p&gt;
