In the present study, biogenic silver nanoparticles (biogenic Ag-NPs) have been synthesized and deposited in situ on an anodized aluminum oxide surface using an ultrasound-assisted onion extract synthesis process. Morphological features and chemical composition have been characterized using scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDS), X-ray diffraction (XRD) spectroscopy, UV-Vis absorption spectroscopy and attenuated total reflection-Fourier transform infrared (ATR-FTIR) spectroscopy. The biogenic Ag-NP-coated anodized aluminum exhibited 100% E. coli bacteria inactivation under 60 minutes of contactenantibacterial propertiesUltrasonic–biogenicsilverArticle
