Antibacterial Activity of ZnSe, ZnSe-TiO 2 and TiO 2 Particles Tailored by Lysozyme Loading and Visible Light Irradiation

ZnSe, ZnSe-TiO microspheres and nanostructured TiO obtained by hydrothermal and sol-gel methods were tested against ATCC 25923 and ATCC 4698 before and after lysozyme (Lys) loading. Morphological characterization of inorganic matrices and hybrid organic-inorganic complexes were performed by microsco...

Description
Summary:ZnSe, ZnSe-TiO microspheres and nanostructured TiO obtained by hydrothermal and sol-gel methods were tested against ATCC 25923 and 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-TiO and TiO powders were assessed by UV-visible spectroscopy and their ability to generate reactive oxygen species (•OH and O ) under visible light irradiation was investigated. Antibacterial activity of ZnSe, ZnSe-TiO , TiO , Lys/ZnSe, Lys/ZnSe-TiO and Lys/TiO samples under exposure to visible light irradiation (λ > 420 nm) was tested against and and correlated with ROS photogeneration.
