Dna Hybridization Detection With Blue Luminescent Quantum Dots And Dye-Labeled Single-Stranded Dna

A simple DNA sensing platform was developed based on the fluorescence resonance energy transfer (FRET) between blue-luminescent CdTe QDs and dye-labeled ssDNA. A cationic polymer acts as a "bridge" to bring the donor to acceptor together and achieves the high FRET efficiency. The hybridization event was recognized by the different FRET ef...更多
