Abstract

Antimicrobial photodynamic therapy strives for creation new photosensitizes providing effective formation of singlet oxygen at irradiation in various spectrum areas. Construction of a new generation of photosensitizes on the basis of nanoparticles, such as TiO₂, Ag, Au, SiO₂ have great potential. We have showed that different nanoparticles used as photosensitizes lead to different effects during photodynamic action. Interaction of broadband light and Ag-SiO₂ nanoparticle film decreased bacterial CFU. Irradiation of the test-cultures, photosensitized by TiO₂, stimulates microbial cell division.
