We report the design, synthesis, and characterization of a binary oligonucleotideprobe for selective DNA or RNA detection. The probe is based on fluorescence resonance energy transfer (FRET) from quantum dot (CdSe/ZnS core shell) DNA conjugates to organic dye (cyanine-5) DNA conjugates. Selective hybridization of the donor/acceptor DNA conjugates to target DNA enhances FRET and a change in fluorescence signature was observed.
