Peculiar Role of the Metallic States on the Nano‐ M o S ₂ Ceramic Particle Surface in Antimicrobial and Antifungal Activity

This study concerns the interactions of two chemically different materials h BN (covalent‐ionic bonds) and M o S ₂ (covalent‐ionic and dispersive bonds) with bacteria and fungi. The materials used in the study were in the form of micro‐ and nanocrystals. Countable inactivation of microorganisms ( Staphylococcus aureus , Sarcina lutea , Aspergillus niger , Escherichia coli ) took place only in the case of M o S ₂ nanosheets. The authors of the study suppose that the bioactivity of nano‐ M o S ₂ can be associated with the presence of “metallic states,” which are present only on their surface.
