Spherical morphologies were observed using transmission electron microscopy (TEM) and scanning electron microscopy (SEM), with mean diameters determined to be 33 nm. XRD analysis validated the crystalline nature of the nanoparticles, with characteristic peaks at 2 θ values of 38.19°, 44.34°, 46.21°, 64.35°, 77.54°, and 81.39° corresponding to the (111), (200), (211), (220), (311), and (222) planes of face‐centered cubic silver. Synthesized AgNPs demonstrated moderate anti‐ Candida albicans and antibacterial properties against the tested strains. Overall, AgNPs‐treated Staphylococcus aureus and Escherichia coli showed higher levels of cell leakage, protein content, and malondialdehyde concentrations than untreated cells. Molecular docking studies demonstrated strong interactions between silver and microbial proteins, with the highest binding affinity observed for protein 5NG5, followed by 5BNM and 3HUM. 10.1002/open.70237 http://creativecommons.org/licenses/by/4.0/ |
