The present work addresses the green synthesis, biological uses, and catalytic activity of Ag-nanoparticles using the ethnomedical vital medicinal plant <strong><em>Ambrosia Artemisiifolia (</em></strong>AA). Several traditional techniques, including powder X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), and ultraviolet-visible spectroscopy (UV–Vis), are employed to validate the formation. To measure the particle size, Dynamic Light Scattering (DLS) and Scanning Electron Microscope (SEM) have been used, and the average particle size is measured as 37.45 nm from SEM and 86.54 nm from the DLS study. Following comprehensive characterization, several biophysical investigations, including UV spectroscopic titration, fluorescence displacement assessment, are used to investigate the interaction of the synthesized nanoparticles with Deoxyribonucleic Acid (DNA) and Human Serum Albumin (HSA) protein. High binding constant values of 10⁴ order among nanoparticles and macromolecules indicate a strong affinity of the developed nanoparticles with DNA and proteins. The results of the fluorescence displacement study confirm the groove binding mode of interaction between AgNPs and DNA, whereas the thermodynamic parameter values confirm the hydrophobic interaction among AgNPs with HSA protein. The results of the traditional MTT assay on HeLa cancer cells and HEK 293 normal cells support the anticancer effect of the nanoparticles with low toxicity to normal cells. Besides, AgNPs showed 75.48 % antioxidant activity, outperforming the plant extract by 27.95 %, demonstrating enhanced antioxidant properties..
