Abstract

A series of experimental studies on lethal photosensitization of microorganisms most often met in suppurative wounds 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 in the active medium.
