Abstract
ABSTRACTCapillary electrophoresis with fluorescence detection was used to characterize the self-assembly of cadmium selenide–zinc sulfide quantum dots and a cyanine5-labeled peptide (cyanine5-EAAAAAHHHHHH). The self-assembly was driven by metal-affinity forces to allow characterization by Förster resonance energy transfer. The Förster resonance energy transfer signal increased with the ratio of cyanine5-EAAAAAHHHHHH to quantum dots and reached a plateau at a ratio of 32:1. This method illustrates the application of quantum dot-based bioanalysis.
