Melamine (MEL) adulteration is a major global concern due to its cytotoxic effects, especially in infants, toddlers, and adults via food, from milk dairy products. Thus, robust, reliable, sensitive sensing platform needed for ultra-low detection of MEL milk. Zn-Salophen (Zn-Sal) complexes nanoparticles have gained much attention their excellent electro-catalytical properties, high conductivity, large surface area, ease synthesis. The presented study successful approach develop novel Zn-Sal/CuO Nanoflakes (Nfs) nanohybrid on pencil graphite electrode-based electrochemical sensor MEL. structural morphology composite individual materials was elucidated by Fourier-transform infrared spectroscopy, powder X-ray diffraction, field-emission scanning electron microscopy, thermogravimetric analysis, differential calorimetry. relied electroactive Cu-MEL coordination, which enhanced charge transfer conductivity. proposed exhibits recovery rate ranging 101.25 99.5% spiked samples with broad linear range 0.01–1300 nM limit as low 0.006 nM. sensitivity selectivity the towards make it reliable tool
