  • Title: CdSe/ZnS quantum dots-G-quadruplex/hemin hybrids as optical DNA sensors and aptasensors.
    Author: Sharon E, Freeman R, Willner I.
    Journal: Anal Chem; 2010 Sep 01; 82(17):7073-7. PubMed ID: 20695436.
    Abstract:
    The luminescence of CdSe/ZnS QDs is quenched via electron transfer by hemin/G-quadruplex associated with the particles. This phenomenon is implemented to develop DNA sensors or aptasensors by tailoring hairpin-functionalized QDs that generate the hemin/G-quadruplex quenchers upon sensing of the respective analytes.
