Recent development of an electrochemical imprinted sensor for the detection of trace-level of unmetabolized aflatoxin B2 in dairy milk

Herein, we present and discuss the development of a novel sensor for aflatoxin B2 (AFB2) determination by two methods of functionalization. The first method was performed, by the electrodeposition of zinc oxide nanoparticles (ZnO-NPs), coated with a mixture of chitosan (CS) and AFB2 on the gold-working area of a screen-printed electrode. As for the second functionalization method, it was carried out by electropolymerization of pyrrole (Py) and...
