ABSTRACT
Objective To develop a new type of electrochemical immunosensor for the detection of ochratoxin A (OTA ) . Methods Double layers of self‐assembly immunosensor for the detection of OTA were constructed based on the composite single‐walled carbon nanotubes(SWNTs)/chitosan(CS) membrane immobilized on glassy carbon electrode(GC) .Scanning electron mi‐croscopy(SEM) ,square wave voltammetry and cyclic voltammetry were used to analyze the characterization of the sensor ,then its specificity for detection was studied .Results SWNTs/CS composit membrane could increase the sensitivity of OTA detection sig‐nificantly ,and effectively distinguish the different types of mycotoxins .Conclusion The electrochemical immunosensor developed in the study is easy to operate and could detect OTA rapidly with good specificity and low detection limit .
