Chromatic-Zone Mapping for Rapid Discovery of Antibacterial Alloys with Nanostructured Surfaces.

ABSTRACT: Addressing antibiotic-resistant bacteria requires the efficient development of antibiotic-free antimicrobial materials. Herein, a high-throughput parallel chromatic-zone screening strategy is developed that enables the simultaneous screening of composition and surface structure, thereby optimizing antimicrobial performance. As an example, a MgCuPdGd alloy library with diverse compositions and nanostructures, consisting of 229 samples with continuous compositional gradients and varied nanostructured morphologies is constructed by integrating magnetron co-sputtering and chemical dealloying. The dealloyed samples exhibit distinct chromatic zones-red, yellow, and green-each associated with unique compositional and microstructural features. Among these regions, the red Cu-rich region demonstrat
