•Green synthesis of AgNPs nanoparitcles using Hardwickia binata.•The synthesized AgNPs were characterized by UV, XRD, IR, FE-SEM-EDAX, and HR-TEM with SAED pattern.•The synthesized AgNPs shows a Spherical shape of nanoparticles.•The synthesized AgNPs demonstrated excellent biological & photo-catalytic activities. In this study, synthesized AgNPs were produced using an aqueous leaf extract of Hardwickia binata. The highest absorption wavelength was found to be at 454 nm. The study evaluated the antibacterial activity of the synthesized AgNPs and found that they exhibited the highest zone of inhibition against B. subtilis, indicating good antibacterial activity. The antioxidant activity evaluated using DPPH, ABTS assays and further analyzed the synthesized AgNPs for their anti-inflammatory and anti-proliferative activity. In an environmental related study, the degradation of Methylene Blue (MB) dye using the synthesized AgNPs. The results showed that the MB dye was completely degraded within 210 min, suggesting that the synthesized AgNPs have potential as treatment option for dye-containing wastewater. The findings of the study synthesized AgNPs the antioxidant, anti-inflammatory, anticancer and good dye degradation properties. The current research holds promise for addressing the issue of removing hazardous dyes from wastewater discharged by many industries.
