Calibration curves were constructed to determine the concentrations of arginine in model solutions. The lower limit of sensitivity of the developed biosensor to arginine was 0.5 µM, the linear range of 0.01-4 mM, the dynamic range of 0.01-8 mM. The high specificity of the biosensor system to arginine is shown, and its selectivity in the presence of a number of amino acids.      The methodical recomentation on laboratory work "Method of electrochemical impedance spectroscopy" was prepared for students of the Institute of high technologies, NSC "Institute of Biology and Medicine" and the Faculty of Radiophysics, Electronics and Computer Systems of the Taras Shevchenko National University of Kyiv.
