Applied Surface Science, 746, 167591. https://doi.org/10.1016/j.apsusc.2026.1675910169-43321873-5584https://hdl.handle.net/11268/17234Cu-Au core-nanocluster nanoparticles (NPs) offer a promising platform for multifunctional antimicrobial materials through coupled oxygen reduction, reactive oxygen species (ROS) generation, and galvanically enhanced ion release. Here, the interfacial mechanisms governing antimicrobial activity in CuAux NPs are investigated using structural characterisation, density functional theory (DFT), electrochemical analysis, and antibacterial testing.engAttribution 4.0 Internationalhttp://creativecommons.org/licenses/by/4.0/Ingenieríasjournal article10.1016/j.apsusc.2026.167591open accessOxígenoCorrosiónIngenieríaGoal 9: Build resilient infrastructure, promote sustainable industrialization and foster innovation
