quantum dots, nanocrystals, capillary electrophoresis

Characterization of nanocrystals is crucial for the development of many chemical methods based on this technology. For this, there are several techniques, mainly microscopic, and recently capillary electrophoretic techniques, that have been proposed. In our laboratory, we examined several capillary electrophoretic methodologies: zone (CZE), micellar (MEKC), microemulsion (MEEKC), non-aqueous (NACE) and polymer based (CGE). For the separation of water soluble CdSe nanocrystals, CZE, MEKC and CGE were found to be suitable
