New Gypsum-Titanium Composites for Antimicrobial Photocatalytic Action on Staphylococcus aureus

The last decade has allowed the creation of new composite photocatalytic materials with a wide range of applications. Antimicrobial coatings based on photocatalytic materials are environmentally friendly and effective for use in health care, the food industry, enterprises and service facilities. This study is devoted to the study of the antibacterial activity of gypsum-titanium nanocomposites.

Photocatalytic effect of led radiation (405 nm) and new Al2O3 3D-nanocomposites on the growth of Staphylococcus aureus

The progressive growth of bacterial resistance to antibiotic drugs requires the creation of highly efficient nanomaterials. Aluminum oxide is a stable non-toxic semiconductor material; however, the photocatalytic properties of its modifications in relation to microorganisms are not well understood. In this study, we used new 3D composites of aluminum oxyhydroxide (Al2O3 ? nH2O) in three modifications (?, ? and ?), which are a mesh of 150 nm nanofibrils.
