The CE instruments were laboratory\u2010built, each being capable of both electrokinetic and hydrodynamic injection. Modes of detection include UV absorption and LIF. The CE\u2010LIF system was further modified to handle microliter sample volumes during injection. Sodium phosphate (5\u201325\u2005mM, pH\u20057.5\u201311) was found to be a good buffer electrolyte. Sodium mercaptoproprionate CdTe\/CdS (ADS620) QDs and carboxylic acid CdSe\/ZnS (T2\u2010Evitag) QDs yielded high separation efficiencies of <jats:italic>N<\/jats:italic>\u2005=\u20051.5\u00d710<jats:sup>6<\/jats:sup> plates at <jats:italic>t<\/jats:italic><jats:sub>M<\/jats:sub>\u2005=\u200510\u2005min and <jats:italic>N<\/jats:italic>\u2005=\u20051.0\u00d710<jats:sup>5<\/jats:sup> plates at <jats:italic>t<\/jats:italic><jats:sub>M<\/jats:sub>\u2005=\u20053.8\u2005min, respectively. Apparently the EDC\/sulfo\u2010NHS bioconjugation chemistry worked well with the neutral T2\u2010Evitag QDs, but not so well with the negatively charged ADS620 QDs. This preliminary knowledge will serve as a basis for new CE immunoassay studies of QD\u2010biomolecule conjugates and their immunocomplexes with target analytes.<\/jats:p>","DOI":"10.1002\/elps.200600737","type":"journal-article","created":{"date-parts":[[2007,7,23]],"date-time":"2007-07-23T10:46:38Z","timestamp":1185187598000},"page":"2874-2881","source":"Crossref","is-referenced-by-count":39,"title":["Characterization of quantum dots using capillary zone electrophoresis"],"prefix":"10.1002","volume":"28","author":[{"given":"Mark","family":"Pereira","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Edward P.
