Multi-analyte homogenous immunoassay based on quenching of quantum dots by functionalized graphene
We propose a homogenous multi-analyte immunoassay based on the quenching of quantum dot (QD) fluorescence by means of graphene. Two QDs with emission maxima at 636 and 607 nm were bound to antibodies selective...
