Paper Abstract

The main goal was to study the sensitivity of microorganisms to combined action of LED blue (405 nm) light and iron oxides nanoparticles. The bacterial strain used in this study was Staphylococcus aureus 209 P. As blue light source LED with spectrum maxima at 405 nm was taken. The light exposure was ranged from 5 to 30 min. Fe2O3 nanoparticles with average size about 7 nm and Fe3O4 with average size about 6 nm in concentration of 0.001% were used. It was shown that irradiation with blue light caused 20 to 88% decrease in the number of microorganisms treated with nanoparticles.
