Therefore, stringent monitoring of IC content in food is essential to ensure public health and safety. In this study, we developed a novel electrochemical sensor for IC detection by synthesizing a nanocomposite of zirconium-based metal-organic frameworks (Zr-MOF) and multi-walled carbon nanotubes (MWCNTs). The Zr-MOF@MWCNTs composite was characterized by scanning electron microscopy (SEM), transmission electron microscope (TEM), Fourier-transform infrared spectroscopy (FT-IR) and X-ray photoelectron spectroscopy (XPS). The sensor leverages the synergistic combination of the electrocatalytic properties of Zr-MOF and the superior conductivity of MWCNTs, demonstrating rapid response, excellent selectivity, high sensitivity (4.484 μA μM<sup>-1</sup> cm<sup>-2</sup>), a broad detection range (0.005–30.0 μM), and a low limit of detection (LOD, 3.0 nM).
