Abstract
The main goal was to study the sensitivity of microorganisms to combined action of LED blue (405 nm) light and Fe2O3 nanoparticles. The bacterial strains used in this study were Staphylococcus aureus 209 P, S. simulans, Dermabacter hominis (isolated from maxillary sinusitis). 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 8 nm in concentration of 0.001% were used. It was shown that irradiation with blue light caused 20 to 90% decrease in the number of microorganisms treated with nanoparticles.
