“…Thus, this process has been employed in the fabrication of metal microstructures with welldefined shapes, such as nanorod arrays [44,45], nanosheets [46], pyramids [47], flower-like particles [48] and dendrites [49]. Some studies report about the electrodeposition of silver structures on indium tin oxide (ITO) [50,51], but also on aluminum [52] and anodized aluminum surfaces [53,54].…”

The emergence and spreading of the SARS-CoV-2 pandemic has forced the focus of attention on a significant issue: the realization of antimicrobial surfaces for public spaces, which do not require extensive use of disinfectants. Silver represents one of the most used elements in this context, thanks to its excellent biocidal performance. This work describes a simple method for the realization of anodized aluminum layers, whose antimicrobial features are ensured by the co-deposition with silver nitrate. The durability and the chemical resistance of the samples were evaluated by means of several accelerated degradation tests, such as the exposure in a salt spray chamber, the contact with synthetic sweat and the scrub test, highlighting the residual influence of silver in altering the protective behavior of the alumina layers. Furthermore, the ISO 22196:2011 standard was used as the reference protocol to set up an assay to measure the effective antibacterial activity of the alumina-Ag layers against both Gram-positive (Staphylococcus aureus) and Gram-negative (Escherichia coli) bacteria, even at low concentrations of silver. Finally, the Ag-containing aluminum oxide layers exhibited excellent antimicrobial performances also following the chemical–physical degradation processes, ensuring good durability over time of the antimicrobial surfaces. Overall, this work introduces a simple route for the realization of anodized aluminum surfaces with excellent antibacterial properties.

SummaryMetal nanocages have raised great interest because of their new properties and wide applications. Here, we report on the use of galvanic replacement reactions to synthesize substrate-supported Ag–Au nanocages from silver templates electrodeposited on transparent indium tin oxide (ITO) film coated glass. The residual Ag in the composition was dealloyed with 10% nitric acid. It was found that chains of Au nanocages were formed on the substrate surface during dealloying. When the concentration of HNO3 increased to 20%, the structures of nanocages were damaged and formed crescent or semi-circular shapes. The transfer process on the substrate surface was discussed.

“…In our previous reports [23][24][25], we have electro-deposited template silver nanoparticles (AgNPs) on ITO substrates and carried out the galvanic replacement reactions. Figure 1 shows top-view and tilted-view SEM images of unreacted AgNP templates and those exposed to aqueous 0.1 mM HAuCl 4 solution for 2 h. Prior to the reaction the Ag templates show a morphology characteristic of semi-spheres in contact with a surface ( Figure 1A).…”
