Abstract:
The design and fabrication of high-touch surfaces with antibacterial properties can reduce microbial
burden and subsequent nosocomial infections in a hygiene-critical environment. 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 contact
