The soliton mechanism of the delayed luminescence of biological systems

Soliton model is suggested to explain the main properties of the delayed lu minescence spectra of simple biological systems. Solitons describe self-tra pped localised electron or exciton states in low-dimensional biological mac romolecules, like alpha-helical proteins, actin filaments, microtubules, et c., and provide charge and energy transport on macroscopic distances in mai n biological processes. Such a model explains the long duration of the dela yed luminescence of bio-systems, its kinetics and dependence on the intensi ty of the stimulating light.
