Quenching of CdSe quantum dot emission, a new approach for biosensing

Chem Commun (Camb). 2005 Jul 7:(25):3201-3. doi: 10.1039/b500664c. Epub 2005 May 20.

Abstract

The emission of CdSe quantum dots linked to the 5'-end of a DNA sequence is efficiently quenched by hybridisation with a complementary DNA strand with a gold nanoparticle attached at the 3'-end; contact of the quantum dot and gold nanoparticle occurs.
