Abstract Using a trustworthy electrochemical sensor in the detection of urea real blood samples received great attention these days. A thin layer nickel-coated nickel-manganese (Ni@NiMn) is electrodeposited on glassy carbon electrode (GC) (Ni@NiMn/GC) surface and used to construct for detection. Whereas, electrodeposition considered as strong technique controllable synthesis nanoparticles. Thus, X-ray diffraction (XRD), atomic force microscope (AFM), scanning electron (SEM) techniques were characterize produced electrode. AFM SEM pictures revealed additional details about morphology, which homogenous smooth coating. Furthermore, research was carried out alkaline medium utilizing various methods, including cyclic voltammetry (CV), chronoamperometry (CA), impedance spectroscopy (EIS). The investigations showed that had good performance, high stability effective charge transfer capabilities. structural, morphological, characteristics Ni@NiMn/GC electrodes well understood using analytical techniques. limit (LOD) equal 0.0187 µM linear range 1.0–10 mM urea. examine efficiency prepared sensor. Otherwise, anti-interfering ability modified catalyst examined toward interfering species.
