In the present work, we designed a disposable voltammetric sensor utilizing a manganese ferrite nanoparticles -modified screen-printed electrode (MF/SPE) for epinine determination. The electrochemical behavior of EP at the MF/SPE was examined using differential pulse voltammetry (DPV), cyclic voltammetry (CV), and chronoamperometry techniques. The MF/SPE exhibited outstanding electro-catalytic activity for the voltammetric detection of EP. Under optimized conditions, the peak current showed a linear dependence with the concentration of EP in the range of 0.1 to 600.0 µM, and a detection limit (LOD) of 0.02 µM was determined. In addition, the MF/SPE sensor has advantages including repeatability, reproducibility, stability, inexpensiveness, and practical application. Finally, the MF/SPE -based sensor was utilized for the determination of EP in the real urine samples and the satisfactory results were obtained.
