“…At present, many methods have been developed to detect CBZ, including high-performance liquid chromatography (HPLC) [ 6 ], ultraviolet–visible spectrophotometry [ 7 ], capillary electrophoresis [ 8 ], fluorescence spectrometry [ 9 ], and electrochemical analysis [ 10 ]. Although sensitive and reliable, some methods have some drawbacks, such as complex sample pretreatment, high operation requirements, long detection time, and expensive instruments which are difficult to apply to rapid detection and on-site analysis of pesticide residues [ 11 , 12 ]. As a supplement, the electrochemical method is widely used in the detection of pesticide residues because of its low cost, high sensitivity, and simple operation [ 13 , 14 ].…”

Carbendazim (CBZ) abuse can lead to pesticide residues, which may threaten the environment and human health. In this paper, a portable three-electrode sensor based on laser-induced graphene (LIG) was proposed for the electrochemical detection of CBZ. Compared with the traditional preparation method of graphene, LIG is prepared by exposing the polyimide film to a laser, which is easily produced and patterned. To enhance the sensitivity, platinum nanoparticles (PtNPs) were electrodeposited on the surface of LIG. Under optimal conditions, our prepared sensor (LIG/Pt) has a good linear relationship with CBZ concentration in the range of 1–40 μM, with a low detection limit of 0.67 μM. Further, the sensor shows good recovery rates for the detection of CBZ in wastewater, which provides a fast and reliable method for real-time analysis of CBZ residues in water samples.
