Аннотация:It is shown that semiconductor nanocrystals (or quantum dots) can be used to increase the absorbability of a pigment protein. In the mixture of phycoerythrin with quantum dots, the fluorescence of the quantum dots is suppressed several times due to the transfer of absorbed energy to phycoerythrin. The Forster resonance energy transfer is discussed as a possible mechanism of energy transfer in quantum dot-phycoerythrin donor-acceptor pairs. Calculations based on experimental data show that the efficiency of energy migration from quantum dots to phycoerythrin is 88% and the corresponding rate constant is 1.17 × 109 s−1.
