Photodynamic aspects of antimicrobic action of silvernanoparticles on Staphylococcus aureus strains

摘要

The study of antimicrobial photodynamic activity of subingibing concentrations of aqueous solutions of silvernanoparticles under the photodynamic action of blue led radiation in relation to the standard and clinical strain ofStaphylococcus aureus. The greatest sensitivity to the combined effects of radiation and metal nanoparticles showedmethicillin-resistant clinical strain of Staphylococcus aureus. The samples containing silver nanoparticles presented inthe experiment were characterized by a pronounced antimicrobial activity and can be considered as promisingphotosensitizers for photodynamic therapy of pyoinflammatory diseases.
