Abstract

We studied photodynamic action of LED radiation (660 nm) sensitized by Methylene Blue on bacteria strain Staphylococcus 209 P. Method efficiency was compared with photodynamic action of He-Ne laser radiation (632,8 nm). Methylene Blue was proved to possess good photosensitizing properties and its application in photodynamic therapy of pyoinflammatory diseases was found advantageous.
