Miniaturized label-free impedimetric immunosensor for analysis of aflatoxin B1 in peanut

Abstract

A highly sensitive and selective label-free impedimetric immunosensor based on silver (Ag) wire electrode for the detection aflatoxin B1 (AFB1) in peanut is presented. The sensor was constructed by functionalizing Ag wire coupled with polyclonal antibodies of AFB1 through self assembled monolayers. The antigen-antibody interaction was analyzed by measuring… (More)
