Аннотация:Photophysical properties of quantum dots based on CdSe/ZnS solubilized by L-Cysteine shell, were compared in solutions of cell culture medium and in live and fixed HeLa cells. We show that the luminescence kinetics of nanocrystals in fixed cells were similar to those obtained in the case of intravital samples that is important for adequate interpretation of the data obtained.
Keywords—Quantum dots; L-cysteine; decay times.
