Abstract
Advantages offered by the use of quantum dots (QDs) for the investigation and diagnostics of biological systems are considered. A new method for the QD diagnostics of amino acid is proposed. The interaction of isolated QDs with charged amino acid residues is analyzed. It is shown that this interaction can shift the luminescence spectrum of QDs by several tens of millielectronvolts, which opens broad possibilities for the identification of biological objects with the aid of QDs.
