that can
be chemically attached to thiolated-DNA oligomers and mediate their self-assembly to CdSe-ZnS core-shell QDs. The self-assembly of
hexahistidine-appended DNA to QDs is probed with gel electrophoresis and fluorescence resonance energy transfer techniques, and the
results confirm high-affinity conjugate formation with control over the average molar ratio of DNA assembled per QD.
