| Abstract Scope |
High-traffic touch surfaces are a vector for disease propagation, motivating the need to develop materials that are rapidly self-sanitizing and active against a range of pathogens. A variety of metals have been shown to be highly bioactive; developing an alloy of several bioactive metals may result in a broad-spectrum sanitizing surface which functions by a range of mechanisms. However, many bioactive metals are immiscible, including our targets CuCoAg. Using an entropy stabilization paradigm, alloys of CuCoAgNi were prepared as a metastable alloy, then annealed. Structural and bioactivity testing was performed on several compositions, both as-prepared and annealed. Testing included surrogate microorganisms for human pathogens in several major classes, including enveloped and non-enveloped viruses and gram-positive and negative bacteria. The results emphasize the critical role of the microstructure and copper composition on achieving a sanitizing effect. |
