ABSTRACT
We report on a novel strategy to improve microfluidic immunoassay sensitivity by introducing chemiluminescence resonance energy transfer (CRET) into the immunoreactions. The proposed CRET-based immunoassay for estradiol (E2, as a model analyte) is one of the most sensitive immunoassay with a limit of detection at 3.6 × 10(-11) M E2 in a microfluidic format.
