Аннотация:It is shown that semi-conductor nanocrystals (quantum dots, QD) can be used to increase the absorption capacity of the pigment-protein complexes. In a mixture of the photosystem 2 core complex (PS2) and QD, the fluorescence of the latter decreases in several times due to the transfer of the absorbed energy to the PS2 core complex. We discuss Ferster's inductive-resonance mechanism as a possible way of energy transfer in donor-acceptor pairs QD-PS2 core complex. Calculations based on the experimental data, have shown that the enhancement of PS2 fluorescence and the rate of QA reduction increase up to 60%, due to efficient energy migration from QD to PS2.
