Abstract
Luminol capable of generating electrochemical luminescence was employe d as a label of immunoassay. A luminol-labeled antibody generated lumi nescence upon anodic oxidation and the luminescence decreased markedly in the presence of antigen. The decrease was correlated to the antige n concentration as low as 10(-11) g/ml antigen. The proposed method wa s operated in an optoelectrochemical cell. A miniaturized and sensitiv e immunosensing can be developed by fabricating a small cell with a ve ry thin layer.
