Synthesis and Fabrication of MXene/MWCNT Nanocomposites for Electronic Detection of Sulfamethoxazole

Abstract

The significant demand for accurate and accessible sensors has led to significant advances in nanotechnology. This is especially relevant to the use of advanced nanomaterials; in this study, a hybrid composite of MWCNTs and MXene was produced. The MXene/MWCNT composite was made by sonication procedures and subsequently assessed by using X-ray diffraction (XRD) and field emission scanning electron microscopy (FESEM) to verify successful integration and enhanced structural properties. The produced sensor exhibited a detection limit of 3.053 μg/L and a sensitivity of 2.55 mA μg–1 L. Additionally, it demonstrated exceptional electrical performance and a linear, beneficial response to varying SMX concentrations. This potential of MWCNTs/MXene-based sensors makes them effective tools for detecting pharmaceutical residues with high sensitivity for practical field uses.
