Antibacterial Activity of ZnSe, ZnSe-TiO₂ and TiO₂ Particles Tailored by Lysozyme Loading and Visible Light Irradiation.

ABSTRACT: ZnSe, ZnSe-TiO₂ microspheres and nanostructured TiO₂ obtained by hydrothermal and sol-gel methods were tested against Staphylococcus aureus ATCC 25923 and Micrococcus lysodeikticus ATCC 4698 before and after lysozyme (Lys) loading. Morphological characterization of inorganic matrices and hybrid organic-inorganic complexes were performed by microscopy techniques (SEM, AFM and Dark Field Hyperspectral Microscopy). Light absorption properties of ZnSe, ZnSe-TiO₂ and TiO₂ powders were assessed by UV-visible spectroscopy and their ability to generate reactive oxygen species (•OH and O₂^•-) under visible light irradiation was investigated. Antibacterial activity of ZnSe, ZnSe-TiO₂, TiO₂, Lys/ZnSe,
