摘要

A femtomolar digital homogenous immunoassay is developed based on sensitively distinguishing the immunocomplexes labeled with quantum dot (QD) aggregates from the excessive free monodisperse single QDs. The success in quantifying the carcino-embryonic antigen and alpha-fetoprotein in plasma validated the feasibility of our approach for clinical tests.
