Microbiological evaluation Ag-doped coatings glass substrates confirmed their significant bactericidal activity against Gram-negative Escherichia coli. Among types coatings, impregnated demonstrated most promising performance, evidenced both EIS analyses.

In this study, we investigated the influence of crystal structure, topography, and elemental composition aluminum oxide surfaces on bacterial adhesion. The structural properties were systematically controlled by varying current density (1.5, 2.0, 2.5 A/dm2) silver doping during anodization process. resulting changes in morphological examined using X-ray diffraction (XRD), photoelectron spectroscopy (XPS), field emission scanning electron microscopy (FE-SEM), contact angle measurements, profilometry. Using FE-SEM analysis, evaluated adhesion model bacteria, Escherichia coli Staphylococcus aureus, to exhibiting diverse morphologies compositions. surface roughness size increased proportionally with applied doping. According XRD results, slip plane structure (311) but decreased Specifically, while stepped atomic alignment planes facilitates attachment, smoother (200) reduce adhered bacteria population. Further analysis via XPS revealed that undoped shifted from tetrahedral octahedral form increasing density, silver-doped exhibited opposite trend. Additionally, preparation diminished ratio ionic metallic silver, suggesting a lowered propensity for S. aureus 4.46-fold prepared at A/dm2 compared 1.5 A/dm2. Moreover, E. was completely inhibited anodized Reducing incorporating decrease number adhering surfaces.
