In this work,a novel immunosensor was constructed based on the alkaline phosphatase(ALP)in situ generating an electroactive substance by enzymatic hydrolysis the inactive substrates.The new signal-amplified strategy for sensitive detection of HIgG was based on the catalytic oxidation of ALP-generated products,ascorbic acid(AA),using carbon-based Ag-Au bimetallic as the catalyst and signal enhancer.
