In this report, fluorescence detection coupled capillary electrophoresis (CE-FL) was used to detect Protein A. Antibody was first labeled with Cy5 and then mixed with quantum dots (QDs) to form QDs-antibody bioprobe. Further, we observed fluorescence resonance energy transfer (FRET) from QDs donor to Cy5 acceptor. The bioprobe was formed and brought QDs and(More)
Multiphoton-excited fluorescence by diode laser of continuous wave was uniquely developed for capillary electrophoresis to determine aniline species metabolized from pesticides. To achieve 2-photon excitation fluorescence, derivatization procedure was performed using fluorescein isothiocyanate (FITC). The concentration ratio of FITC to the analytes was(More)
We present a molecular characterization of metal-affinity driven self-assembly between CdSe-ZnS quantum dots and a series of hexahistidine peptides with different charges. In particular, we uti- lized fluorescence coupled capillary electrophoresis to test the self-assembly process of quantum dots with peptides in solution. Four peptides with different(More)
