© 2020, Springer-Verlag GmbH Austria, part of Springer Nature.This work presents the development of disposable biosensors used in the determination of biogenic amines. The biosensors were fabricated using diamine oxidase (DAOx) or monoamine oxidase (MAOx) enzyme- and platinum nanoparticle (PtNP)-modified screen-printed carbon electrodes (SPCE). The morphological and electrochemical properties of the biosensors were examined by scanning electron microscopy, energy-dispersive X-ray spectroscopy, electrochemical impedance spectroscopy, and cyclic voltammetry measurements. Amperometric measurements indicated that the DAOx/PtNP/SPCE biosensor responded to histamine, putrescine, cadaverine, spermine, spermidine, β-phenylethylamine, tryptamine, and tyramine; however, its MAOx-based counterpart showed no response towards putrescine and cadaverine. A performance comparison of two biosensors indicated that the one based on DAOx had a linear concentration range from 5.3 × 10− 7 to 7.2 × 10− 5 M and the other based on MAOx from 3.9 × 10− 7 to 7.6 × 10− 5 M for tyramine. The sensitivities of the DAOx- and MAOx-based biosensors towards tyramine were 24.8 µA mM− 1 and 46.1 µA mM− 1, respectively. The proposed biosensors were tested for analysis of blue cheese sample spiked with known concentration of tyramine for the verification of biosensor applicability for real samples.
