ВЛИЯНИЕ СВЕТОДИОДНОГО СИНЕГО (405 нм) ИЗЛУЧЕНИЯ И НАНОЧАСТИЦ ОКСИДА ЖЕЛЕЗА (III) НА ВЫЖИВАЕМОСТЬ И МОРФОЛОГИЮ КЛЕТОК STAPHYLOCOCCUS AUREUS 209 P

Изучено влияние светодиодного синего (405 нм) излучения в
сочетании с оксидом железа III на бактерии Staphylococcus aureus
209 P. Показано, что синий (405 нм) свет в сочетании с
наночастицами Fe2O3 обладал угнетающим действием: сниже-
ние численности исследуемых микроорганизмов отмечено на
88% после 30 мин воздействия. Методами атомно-силовой и
электронной микроскопии установлено изменение морфологии
клеток стафилококка при комплексном влиянии синего (405 нм)
излучения и наночастиц Fe2O3
