Ternary and Quaternary Nanocrystalline Cu-Based Sulfides as Perspective Antibacterial Materials Mechanochemically Synthesized in a Scalable Fashion.

ABSTRACT: Twelve Cu-based ternary (Cu-Me₁-S, Me₁ = Fe, Sn, or Sb) and quaternary (Cu-Me₂-Sn-S, Me₂ = Fe, Zn, or V) nanocrystalline sulfides are shown as perspective antibacterial materials here. They were prepared from elemental precursors by a one-step solvent-free mechanochemical synthesis in a 100 g batch using scalable eccentric vibratory ball milling. Most of the products have shown strong antibacterial activity against Escherichia coli and Staphylococcus aureus bacteria. For instance, stannite Cu₂FeSnS₄ and mohite Cu₂SnS₃ were the most active against E. coli, whereas kesterite Cu₂ZnSnS₄ and rhodostannite Cu₂FeSn₃S₈ exhibited the hig
