Abstract

A new mechanism of memory cell formation on structural biological units of the α-helical protein molecules is suggested in this work. The role of Frenkel excitons and "Davydov splitting" in the resonance mechanism of external excitation energy transmission along peptide groups is defined. Using the Green function method was obtained the theoretical bases of the protein cell absorptive power formation under external laser irradiation. The polarization peculiarities of α - protein exciton excitations at such levels of pumping, which allow to obtain a complex outlet signal reaction, were studied. Protein molecules can serve as perspective material for observing the effect of optical bistability. The results of the performed investigations permit to develop one of the lines of the molecular engineering technologies - the creation of molecular memory devices by controlling the laser radiation of the outlet protein molecule.
