Photodynamic/photocatalytic effects on microorganisms,processed by nanodyes

摘要

Photodynamic therapy uses laser, LED or lamp light sources in combination with dyes – exogenous photosensitizers for the enhancement and localization of photodynamic effects within the human body. We are developing a new approach of improvement of the efficiency of antimicrobial phototherapy via combined application of photosensitizers and the photocatalysts to pathogenic microorganisms. The main goal of the paper is to conduct experiments to study the action of nanodyes, based on mixtures of nanoparticles and photosensitizers, in combination with LED irradiation of pathogens.
