Electrochemical sensor for selective tyramine determination, amplified by a molecularly imprinted polymer film

A molecularly imprinted polymer (MIP) film based electrochemical sensor for selective determination of tyramine was devised, fabricated, and tested. Tyramine is generated in smoked fermented food products. Therefore, it may serve as a marker the rottenness these Importantly, intake large amounts by patients treated with monoamine oxidase (MAO) inhibitors lead to “cheese effect”, namely, dangerous hypertensive crisis. The limit detection at S/N = 3 chemosensor, both differential pulse voltammetry (DPV) impedance spectroscopy (EIS) determinations, use Fe(CN)64-/Fe(CN)63- redox probe, 159 168 µM tyramine, respectively. linear dynamic concentration range 290 2.64 mM tyramine. chemosensor highly respect glucose, urea, creatinine interferences. Its DPV determined apparent imprinting factor 5.6. Moreover, mechanism “gate effect” operation film-coated electrodes unraveled.
