Summary: Graphdiyne (GDY) has been widely applied in electrochemical sensing due to its large conjugation system, porous structure, and high structure defects. In this study, conductive MWCNTs were added to enhance the sensing effect of GDY. By using polydopamine (PDA) as a connecting bridge, a stable composite material GDY@PDA/MWCNTs-NH2 was formed and used as an electrochemical sensor for benomyl (Ben) detection. The sensor exhibited a wide linear range, low detection limit, high stability, repeatability, reproducibility, and selectivity, making it suitable for detecting Ben in apple and cucumber samples.

Summary: A new electrochemical impedimetric sensor for direct detection of urea was developed using nanostructured screen-printed electrodes modified with CuO/Co3O4 @MWCNTs. The sensor exhibited a picomolar sensitivity and high selectivity for urea detection, with a linear concentration range of 10(-12)-10(-2) M and a lower detection limit of 0.223 pM (S/N = 5). This non-enzymatic sensor represents a significant advancement in urea detection due to its simplicity, portability, and low-cost fabrication.
