Concentration quenching of photo-induced activity of bacteria in the processes of triplet excited states and mechanisms of their deactivation

A series of experimental studies on lethal photosensitization of microorganisms most often met in suppurative wounds (Staphylococcus epidermidis, Proteus mirabilis, Eusherichia coli, Pseudomonas aeruginosa) were carried out. The reason lies in the fact that the processes of reabsorption of energy of excitation are of two-photon nature; generally, the photochemical processes are multiphoton and are followed by recombination of the charged particles (electrons and molecular ions) in the active medium.
