抄録

This paper reports a novel method of signal amplification based on the accumulation of enzymatic fluorescent products at a wall-like structure (immuno-wall) in a microchannel for sensitive immunoassay. We found the function of an immuno-wall as a media for the enrichment of fluorescence molecules. We combined this function with the amplification of the fluorescence signal by an enzymatic reaction to produce a synergistic effect. The performance of the device was evaluated with human C-reactive protein (CRP) as a model target. The limit of detection of CRP was 2.5 pg/mL. This value was approximately 3 orders of magnitude lower than that obtained with a fluorescent dye-labeled antibody (1.7 ng/mL).
